Class 12 Physics NCERT Exemplar Solutions: All Chapters
Every chapter of the Class 12 Physics NCERT Exemplar Problems book, with the chapter-specific solution set linked on each row. The chapter numbering matches the main NCERT textbook exactly, so a student working Chapter 9 in the textbook can pair it with Chapter 9 in the Exemplar.
Why Use Collegedunia's Class 12 Physics NCERT Exemplar Solutions?
The NCERT Exemplar Problems book is the bridge between the main textbook back-exercise and JEE Main / NEET-level practice. Most students who score 85 plus on the CBSE Class 12 Physics boards have worked through at least half of the Exemplar; toppers typically finish the full book at least once. The Exemplar Solutions here make that practice tractable.
- All five question types covered per chapter: Multiple Choice Question Type I (single correct), Multiple Choice Question Type II (multiple correct, the trickiest section), Very Short Answer, Short Answer, and Long Answer. Each question carries a complete step-by-step solution.
- Expert Solution tier on every numerical: below the standard solution, a longer Expert Solution shows the alternative method, the dimensional check, and the sign-convention reasoning a JEE Advanced topper would write.
- Common-mistake annotations: the routine examiner-flagged errors on each problem are called out in red so you can train your eye to spot them before they cost marks.
- JEE Main and NEET cross-references: any Exemplar problem that has appeared (or a close variant has appeared) on JEE Main or NEET in the last five years is tagged with the year and the exam.
- Diagrams redrawn for clarity: the NCERT Exemplar figures are reproduced and re-labelled where the original book's print is unclear.
- Hindi-medium parallel files: every chapter ships with a Hindi-medium solution set, useful for the Hindi-medium JEE or NEET cohort.

Class 12 Physics Chapter-wise Important Questions (Derivations + Numericals)
The five chapter clusters below carry the bulk of the CBSE 2026 Class 12 Physics paper and repeat almost every year. The Derivations column lists the 3-mark and 5-mark derivations that recur in the long-answer section; the Numericals column lists the application-level questions that appear as 2-mark numericals or as numerical-value questions in JEE Main.
| Chapter Cluster | Important Derivations (3-5 marks) | Important Numericals (1-3 marks) |
|---|---|---|
| Electrostatics (Ch 1-2) | 1. Electric field due to a dipole. 2. Torque on a dipole in a uniform field. 3. Capacitance of a parallel plate capacitor with a dielectric. | Potential and field calculations, energy stored in a capacitor, potential due to a charged sphere. |
| Current Electricity (Ch 3) | 1. Wheatstone bridge balance condition. 2. Potentiometer comparison of EMFs. 3. Kirchhoff's laws applications (loop rule). | Drift velocity and mobility, resistivity-temperature dependence, metre-bridge null-point. |
| Magnetism and EMI (Ch 4-7) | 1. Force on a current-carrying conductor in a magnetic field. 2. Faraday's law and induced EMF. 3. AC generator working principle. | Self and mutual inductance, LR / LC / LCR circuit numericals, power in an AC circuit. |
| Optics (Ch 9-10) | 1. Lens maker's formula. 2. Refraction at a single spherical surface. 3. Young's double slit fringe-width derivation. | Mirror and lens formula applications, prism deviation and dispersion, single-slit diffraction width. |
| Modern Physics (Ch 11-13) | 1. Photoelectric effect equation. 2. Bohr's radius and orbital velocity expression. 3. Radioactivity decay law. | Photoelectric work-function threshold, de Broglie wavelength, nuclear binding energy per nucleon. |
The same five clusters appear in JEE Main 2026 with a near-identical question split - the derivations show up as multi-step numerical-value problems, the numericals as single-step MCQs. The Expert's Solution tab on each chapter page works the JEE / NEET-style alternative path alongside the CBSE board-style minimum-steps version.
NCERT EXEMPLAR SOLUTIONS · CLASS 12 PHYSICS
Class 12 Physics - Exam Weightage Across CBSE, JEE and NEET
Class 12 Physics contributes roughly 200 marks combined across CBSE Boards, JEE Main, JEE Advanced and NEET UG, the heaviest science load on the senior-school flagship exams.
Where to Start in the Class 12 Physics Exemplar Solutions Index
The Exemplar is harder than the back-exercise, so the right starting chapter is the one where you have already done the NCERT main back-exercise comfortably. If you are picking by competitive-exam ROI, this order works:
- Chapter 9 Ray Optics (10 board marks, ~30 JEE Main MCQ overlap): the Exemplar MCQ-II questions on lens combinations and microscope-telescope magnification are the highest-frequency JEE / NEET pattern in the book.
- Chapter 3 Current Electricity (6 board marks): the Exemplar SA section on Kirchhoff's-rule circuits and the Wheatstone bridge is more numerically demanding than NCERT and prepares you directly for the JEE Main circuit numericals.
- Chapter 6 EMI and Chapter 7 AC together: the Exemplar LA section here is the most-tested long-answer slot on the CBSE board paper.
- Chapter 4 Moving Charges and Magnetism (6 board marks): the Exemplar VSA section is the conceptual sharpening tool, and the LA section runs straight into JEE Advanced territory.
- Chapters 11 to 13 (Dual Nature, Atoms, Nuclei): lower NCERT difficulty but heavy NEET overlap. The Exemplar MCQ-I and MCQ-II problems for these chapters are almost identical in shape to NEET Physics questions.
- Chapter 14 Semiconductor Electronics: the rationalised chapter is short but the Exemplar covers it fully; the diode and rectifier problems repeat in JEE Main.
Class 12 Physics Exemplar Solutions: PDF Formats
The Exemplar Solutions ship in formats matched to how students actually use practice material.
- HD print-ready PDF: high-resolution diagrams and clear LaTeX-rendered equations, ideal for printing one chapter's solutions as a revision booklet.
- Standard download PDF: compact file size for mobile reading.
- Combined all-chapters PDF: the full Class 12 Physics Exemplar Solutions in one file, useful for offline revision.
- Question-type filtered PDFs: separate files for MCQ-I, MCQ-II, VSA, SA, and LA so a student can practise one type at a time across all chapters.
- Hindi-medium counterpart: chapter-wise Hindi translations using NCERT's own technical vocabulary.
How the Exemplar Solutions Pair with the Other Class 12 Physics Resources
The Exemplar Solutions are an advanced practice tool, not a concept-revision tool. They expect you to already know the chapter; the other resources cover that role.
- Class 12 Physics Exemplar Book PDF: the source publication. The Exemplar Solutions on this page solve the problems printed in that book.
- Class 12 Physics NCERT Solutions: the main back-exercise solved end to end. Finish the NCERT back-exercise before opening the Exemplar; the Exemplar is a difficulty step up.
- Class 12 Physics Notes: the concept revision you should refresh before attempting any Exemplar chapter. Open the Notes whenever an Exemplar question reveals a concept gap.
- Class 12 Physics Formula Sheet: the equation recall reference you keep open during Exemplar practice.
- Class 12 Physics NCERT Book PDF: the original textbook, useful for the worked-example notation that the Exemplar problems often build on.
- Class 12 Physics Handwritten Notes: notebook-style concept revision for the final week, after Exemplar practice is complete.
How to Use the Exemplar Solutions Most Effectively
The Exemplar is most useful when you do the problem first and consult the solution only after a genuine attempt. Reading the solution cold trains the wrong habit.
5-STEP METHOD · CBSE TOPPER ROUTINE
How to Use the NCERT Exemplar Solutions - Class 12 Physics
- 1Read the chapter first. Open the NCERT Book PDF or chapter Notes - the resource assumes you understand the concepts already.
- 2Attempt each question on your own. Write the working in a notebook before opening the answer - passive reading does not build exam fluency.
- 3Compare your working to the resource. Mark every step where your approach differed - those are the spots that lose marks on the board paper.
- 4Flag questions taking over 7 minutes. These go on the re-attempt list for the final-week revision pass.
- 5Mark every question that took over 10 minutes. Those are the ones worth a third pass in the final week - Exemplar problems repeat ideas, so the slow ones today become quick ones a fortnight later.
- First pass attempt rule: spend at least 7 to 10 minutes on every SA and LA problem before opening the solution. The friction is where the learning happens.
- Use the standard Solution tier for board prep: the standard step-by-step solution is calibrated to CBSE marking-scheme length and rigour. Use it to verify your working.
- Use the Expert Solution tier for JEE and NEET prep: the longer tier shows alternative methods and the JEE-grade reasoning, including dimensional checks and limit-case verifications.
- Mark every MCQ-II you got wrong: the multiple-correct questions are the highest-difficulty section. Re-attempt your marked questions in the final fortnight before the boards or competitive exams.
- Tag the JEE / NEET cross-referenced problems: the cross-referenced problems in each chapter are the highest-ROI for competitive prep. Solve them twice if you are JEE or NEET focused.
What Each Question Type in the Class 12 Physics NCERT Exemplar Tests
The five question types in the Class 12 Physics NCERT Exemplar Solutions are not just length variations of the same question. Each tier tests a different skill, and the marking pattern on the CBSE board, JEE Main, and NEET maps cleanly onto these types.
- MCQ Type I (single correct): tests whether you can pick the one right answer from four close distractors. The Exemplar MCQ-I distractors are crafted to look right; the correct answer often differs from the obvious choice by a sign or by a factor of 2. JEE Main MCQs are structurally similar.
- MCQ Type II (multiple correct): the hardest section. Two or more options can be right, and partial credit is rare. The Class 12 Physics NCERT Exemplar Solutions for MCQ-II problems explain why each option is correct or incorrect, training you to read every distractor independently.
- Very Short Answer (VSA): 1 to 2 mark questions that test the conceptual distinction between similar quantities. A typical VSA asks the difference between magnetic flux and magnetic field, or why the Bohr model fails for multi-electron atoms.
- Short Answer (SA): 3-mark numericals or 3-mark derivations that map directly onto the CBSE Section B and C question slots. The Exemplar SA section is the closest in form to the real board paper.
- Long Answer (LA): 5-mark integrated problems that combine two or three concepts (e.g. EMI plus AC circuit analysis, or Ray Optics plus image formation in compound systems). LA problems prepare you for both the CBSE long-answer slot and the JEE Advanced multi-part questions.
Common Mistakes on Class 12 Physics Exemplar Problems
- Treating MCQ-II as MCQ-I: Multiple Choice Question Type II problems can have more than one correct option. Marking only one option when two are correct loses full marks on that question.
- Skipping the dimensional check: the Expert Solution tier always runs a dimensional check on the final formula. Students who skip this step miss errors that would have been caught in 20 seconds.
- Treating VSA problems as throwaway: the Very Short Answer section often carries the highest-difficulty conceptual distinction in the chapter. Read them as concept gates, not as filler.
- Working the long-answer questions without sketching the figure: the LA section problems in Optics and EMI always reward a clean labelled figure. Sketching first is a 30-second investment for a 2-3 mark return.
- Using the standard Solution tier when JEE / NEET reasoning is needed: the standard tier is calibrated to CBSE rigour. Competitive prep requires the longer Expert Solution tier with alternative-method coverage.
- Skipping cross-referenced JEE / NEET problems: these are flagged for a reason. Most have appeared (sometimes with minor numerical changes) on actual JEE Main or NEET papers in the last five years.

Class 12 Physics NCERT Exemplar Solutions FAQs
Ques. Where can I download the Class 12 Physics NCERT Exemplar Solutions PDF?
Ans. Every chapter-wise Class 12 Physics NCERT Exemplar Solutions PDF is downloadable directly from the index above, from Chapter 1 Electric Charges and Fields through Chapter 14 Semiconductor Electronics. A combined all-chapters compilation plus question-type filtered files (MCQ-I, MCQ-II, VSA, SA, LA) are also linked. Both Normal and HD resolutions are free.
Ques. Are these Class 12 Physics Exemplar Solutions aligned with the 2026-27 NCERT?
Ans. Yes. The solutions reflect the current 2026-27 NCERT Exemplar print. Any problem that was rationalised out of the older edition carries an inline note flagging the change so you do not waste time on out-of-syllabus material.
Ques. How many problems are in the Class 12 Physics NCERT Exemplar?
Ans. Roughly 442 problems across the 14 chapters, split across five question types: MCQ-I (single correct), MCQ-II (more than one correct), Very Short Answer, Short Answer, and Long Answer. The Question Count table above gives the per-chapter breakdown.
Ques. How are the Exemplar Solutions different from the NCERT Solutions?
Ans. The NCERT Solutions work the back-exercise of the main NCERT textbook (the easier set). The NCERT Exemplar Solutions work the harder problems from the separate NCERT Exemplar Problems publication. Exemplar problems are noticeably harder than the textbook back-exercise; the SA and LA sections are closer in difficulty to JEE Main than to a CBSE board paper.
Ques. Are the Exemplar Solutions useful for JEE Main and NEET?
Ans. Yes, very much. Many JEE Main and NEET Physics questions are lifted directly from the NCERT Exemplar or are minor numerical variants of Exemplar problems. The Expert Solution tier on every numerical shows the JEE-grade reasoning a competitive-exam student should write.
Ques. Which Class 12 Physics Exemplar chapter is the hardest?
Ans. The Student Pulse survey flagged Chapter 6 Electromagnetic Induction as the hardest-rated Exemplar chapter (58% of students said the Exemplar problems felt furthest from the NCERT back-exercise). Chapter 9 Ray Optics is a close second, especially in the MCQ-II section.
Ques. Should I do the NCERT back-exercise first or jump straight into the Exemplar?
Ans. NCERT back-exercise first. The Exemplar problems assume you have completed the standard back-exercise and are ready for a difficulty step up. Jumping straight to the Exemplar without the back-exercise foundation usually wastes 30 to 40% of your practice time on concepts the NCERT back-exercise would have covered faster.
Ques. What are MCQ-I and MCQ-II in the Exemplar?
Ans. MCQ-I is a Multiple Choice Question with exactly one correct option. MCQ-II is a Multiple Choice Question where more than one option may be correct; you must mark every correct option to get full marks. MCQ-II is the highest-difficulty section in the Exemplar and the closest in shape to JEE Advanced multi-correct questions.
Ques. Are Hindi-medium Class 12 Physics Exemplar Solutions available?
Ans. Yes. Every chapter ships with a Hindi-medium solution PDF using NCERT's own Hindi technical vocabulary. The Hindi-medium files are particularly useful for the Hindi-medium JEE or NEET cohort since both exams offer Hindi-medium question papers.
Ques. How long should I spend on one Exemplar chapter?
Ans. Plan for 4 to 5 hours on a typical chapter, longer for high-weightage chapters like Ch 9 Ray Optics (around 5 to 6 hours) or Ch 6 Electromagnetic Induction (around 5 to 7 hours). Spread the work across two or three sittings so you can give each problem the 7 to 10 minute first-attempt window before consulting the solution.
Ques. What does the Expert Solution tier add?
Ans. The standard solution tier shows the minimum step-by-step working calibrated to CBSE marking-scheme length. The Expert Solution tier adds the alternative method, dimensional analysis, limit-case verification, and the JEE Advanced-style reasoning that a topper would write. Use the standard tier for CBSE practice and the Expert tier for JEE and NEET preparation.
Ques. Which is the most-scoring Class 12 Physics chapter for board plus competitive prep combined?
Ans. Chapter 9 Ray Optics. It carries 10 marks on the CBSE board, around 2-3 JEE Main questions per attempt, and a consistent NEET appearance. The Exemplar problems for this chapter are the highest-yield 4-5 hour investment in the Class 12 Physics preparation cycle.
