NEET Physics Most Expected Questions with Solutions (Based on Previous Year Trends)

Here are some important NEET physics questions for practise:

Q1. If a physical quantity is given by $P = \frac{a^3 b^2}{c \sqrt{d}}$, and the percentage errors in $a$, $b$, $c$, and $d$ are $1%$, $3%$, $2%$, and $4%$ respectively, what is the percentage error in $P$?

Options:
(1) $2%$
(2) $13%$
(3) $15%$
(4) $10%$

Correct Answer: (2) $13%$

Explanation:
Percentage error in $P$ is:
$ \frac{\Delta P}{P} = 3\frac{\Delta a}{a} + 2\frac{\Delta b}{b} + \frac{\Delta c}{c} + \frac{1}{2}\frac{\Delta d}{d} $
$ = 3(1) + 2(3) + 2 + \frac{1}{2}(4) = 13% $

Q2. Unpolarized light passes through a polarizer. A second polarizer is placed perpendicular to it, and a third polarizer is inserted between them at an angle of $22.5^\circ$. If the intensity after the first polarizer is $I_0$, what is the final transmitted intensity?

Options:
(1) $I_0/4$
(2) $I_0/8$
(3) $I_0/16$
(4) $I_0/2$

Correct Answer: (2) $I_0/8$

Explanation:
Using Malus law:
$I = I_0 \cos^2\theta \cos^2(90^\circ - \theta)$
$= I_0 \cos^2\theta \sin^2\theta = \frac{I_0}{4}\sin^2(2\theta)$
For $\theta = 22.5^\circ$,
$I = \frac{I_0}{8}$

Q 3. Two circular copper coils carry the same current of $2,\text{A}$. If the ratio of their radii is $1:2$, what is the ratio of their magnetic moments?

Options:
(1) $1:2$
(2) $2:1$
(3) $4:1$
(4) $1:4$

Correct Answer: (4) $1:4$

Explanation:
Magnetic moment $M = I \pi r^2$
$\Rightarrow M \propto r^2$
Ratio $= 1^2 : 2^2 = 1:4$

Q 4. A Vernier caliper is used to measure the diameter of a sphere. Given that $10$ vernier scale divisions coincide with $9$ main scale divisions, least count of main scale is $0.1,\text{cm}$, main scale reading is $5,\text{cm}$, the $8^{th}$ vernier division coincides, and the zero error is $+0.1,\text{cm}$, what is the corrected diameter?

Options:
(1) $5.08,\text{cm}$
(2) $4.98,\text{cm}$
(3) $5.00,\text{cm}$
(4) $5.18,\text{cm}$

Correct Answer: (2) $4.98,\text{cm}$

Explanation:
Least count $= 0.1 - 0.09 = 0.01,\text{cm}$
Observed reading $= 5 + 8 \times 0.01 = 5.08,\text{cm}$
Corrected reading $= 5.08 - 0.1 = 4.98,\text{cm}$

Q 5. A photon and an electron (of mass $m$) have the same energy $E$. What is the ratio of their de Broglie wavelengths $\left(\frac{\lambda_{\text{photon}}}{\lambda_{\text{electron}}}\right)$?

Options:
(1) $c\sqrt{2mE}$
(2) $c\sqrt{\frac{2m}{E}}$
(3) $\frac{1}{c}\sqrt{\frac{E}{2m}}$
(4) $\sqrt{\frac{E}{2m}}$

Correct Answer: (2) $c\sqrt{\frac{2m}{E}}$

Explanation:
Photon: $\lambda = \frac{hc}{E}$
Electron: $\lambda = \frac{h}{\sqrt{2mE}}$
Ratio: $\frac{\lambda_p}{\lambda_e} = c\sqrt{\frac{2m}{E}}$

NEET Physics Important Questions 2027 PDF

Students who are appearing in NEET 2027 must practice important Physics questions on a regular basis rather than delaying their revision till a few weeks before the exam date. Practising from a question bank of a particular chapter may prove to be beneficial for them, as it will help them in revising their formulas and the application of concepts.

NEET Physics Important Questions 2027 PDF With Solutions can be used for:

• Revision of important Physics concepts
• Practice of numerical-based questions
• Frequently occurring concepts
• Improving speed and accuracy
• Formula revision and problem-solving technique

Most Important Chapters for NEET Physics 2027

Based on recent NEET paper analysis, some chapters consistently carry more weightage than the rest:

Prepare these chapters properly first before turning to the lower-weightage ones. Don't skip anything entirely - NTA can form NEET questions from those topics of the syllabus students assume are safe to ignore.

How to Practise NEET Physics Important Questions Effectively

Just solving NEET physics important questions will not suffice. Follow a proper revision approach for achieving good results.

Study NCERT First

Always go through NCERT first before solving any question. There are many conceptual questions from NCERT only.

Learn Formula first

Always maintain a separate book of NEET Physics formulas and learn them daily.

Practise by Chapter

Always do one chapter at a time rather than solving random questions.

Analyse Each Mistake

After attempting a paper, always know what mistake you have made in that particular question and revise it.

Solve Previous Year's Papers

Practise NEET previous year papers to increase your speed and precision.

Common Mistakes Students Should Avoid

A surprising number of students lose marks in Physics not because they don't understand the subject, but because of small, avoidable habits that are ignored during practice.

Watch out for these in particular:

• Memorising formulas without actually understanding the concept behind them
• Skipping over NCERT examples and diagrams
• Avoiding previous years' questions because they feel repetitive
• Getting stuck too long on lengthy calculations
• Letting weak chapters go unrevised for too long
• Guessing answers instead of eliminating the obviously wrong options first
• Forgetting units while working through numericals

Fixing even a few of these habits tends to show up in the overall Physics score fairly quickly.

Smart Revision Strategy for NEET Physics 2027

Follow this well-organised revision strategy for gaining clarity on your concepts and achieving better scores in NEET Physics.

• For the start, read the NCERT book completely so that you have an idea about each and every concept before solving NEET Physics important questions.
• Create a formula notebook to memorise all the formulas and revise them time and again so that you can use them comfortably in your exams.
• Solve important questions from each and every chapter so that you get an idea of the kind of questions that are being asked in NEET exams.
• Solve NEET Physics previous years' question papers under a limited amount of time so that you can be well-versed with the exam pattern.
• Take full-length mock tests repeatedly to assess your preparation level and improve your time management skills.
• Analyse all the mock tests and practice sessions carefully, note down your mistakes, and revise all those concepts where you find difficulty.

High-Scoring Tips for NEET Physics 2027

Apply the following practical suggestions while practising important NEET questions and also during your exam.

• Always begin with simple and formula-based questions.
• Answer direct questions from NCERT books first.
• Do not waste your time solving difficult numerical questions.
• Try to eliminate options wherever you can.
• Make sure your calculation is correct before answering.
• Memorise all the important formulas daily.
• Practice at least one Physics test weekly.
• Accuracy should be prioritised over answering all questions.

Why Should You Practise NEET Physics Important Questions?

NEET Physics Important Questions 2027 are to be practised by the candidates in order to:

• Improve their concepts
• Develop problem-solving abilities
• Get acquainted with NEET questions
• Find their weak areas
• Increase speed and accuracy
• Revisit the formulas
• Understand the trend of the questions
• Boost their confidence before the exam

The important questions must be used along with the NCERT books, previous year papers and mock tests. No book can assure you of the NEET questions that may come in NEET 2027.
