NEET Physics Most Asked Questions to Score 150+ Marks

The NEET Physics most asked questions are based on repeated concepts and previous year trends. Practising these important NEET Physics questions 2027 helps improve accuracy, speed, and understanding of exam patterns.

Solve these top NEET Physics questions with solutions to strengthen concepts and increase your chances of scoring 150+ marks.

Q1. The current passing through the battery in the given circuit is:

(a) 1.5 A

(b) 2.0 A

(c) 0.5 A

(d) 2.5 A

Correct answer: (c) 0.5 A

Explanation:

Between points $B$ and $D$, there are two parallel paths.

For path $B-C-D$, resistance $=2.5,\Omega+1.5,\Omega=4,\Omega$.

For path $B-E-D$, resistance $=6,\Omega+1.5,\Omega=7.5,\Omega$.

$\frac{1}{R}=\frac{1}{4}+\frac{1}{7.5}=\frac{11.5}{30}$

$R=\frac{30}{11.5}\approx2.61,\Omega$

$R_{total}=5,\Omega+2.61,\Omega+0.33,\Omega+3,\Omega\approx10,\Omega$

$I=\frac{V}{R}=\frac{5}{10}=0.5,A$

Q2. An electron moving with speed $v=\frac{c}{100}$ enters a magnetic field $B=9 \times 10^{-2} T$ perpendicular to its motion. What electric field must be applied so that the electron moves undeflected?

(a) $\vec{E} | \vec{B}, E=27 \times 10^2 V/m$

(b) $\vec{E} \perp \vec{B}, E=27 \times 10^4 V/m$

(c) $\vec{E} | \vec{B}, E=27 \times 10^4 V/m$

(d) $\vec{E} \perp \vec{B}, E=27 \times 10^2 V/m$

Correct answer: (b) $\vec{E} \perp \vec{B}, E=27 \times 10^4 V/m$

Explanation:

For no deflection:

$qE=qvB$

$\Rightarrow E=vB$

$v=\frac{3 \times 10^8}{100}=3 \times 10^6 m/s$

$E=(3 \times 10^6)(9 \times 10^{-2})=27 \times 10^4 V/m$

The electric field must be perpendicular to $\vec{B}$.

Q3. In a certain camera, a combination of four similar thin convex lenses is arranged axially in contact. Then the power of the combination and the total magnification in comparison to the power and magnification for each lens will be, respectively.

(a) $p, m^4$
(b) $4p, m^4$
(c) $4p, 4m$
(d) $p, 4m$

Correct answer: (b) $4p, m^4$

Explanation:
For lenses placed in contact, powers add algebraically:
$P_{total}=p+p+p+p=4p$
Magnification of lenses in contact is the product of individual magnifications:
$M_{total}=m \times m \times m \times m=m^4$

Q4. Two identical charged conducting spheres $A$ and $B$ have their centres separated by a certain distance. The charge on each sphere is $q$, and the force of repulsion between them is $F$. A third identical uncharged conducting sphere is brought in contact first with sphere $A$ and then with $B$, and finally removed. The new force of repulsion between spheres $A$ and $B$ is:

(a) $\frac{F}{2}$
(b) $\frac{F}{3}$
(c) $\frac{3F}{8}$
(d) $\frac{F}{4}$

Correct answer: (c) $\frac{3F}{8}$

Explanation:
Initial force is
$F=\frac{1}{4 \pi \varepsilon_0} \frac{q^2}{r^2}$
After contact with $A$, the charge on each becomes $\frac{q}{2}$
After contact with $B$, total charge is
$q+\frac{q}{2}=\frac{3q}{2}$
So final charges are
$A=\frac{q}{2}, \quad B=\frac{3q}{4}$
A new force is
$F'=\frac{1}{4 \pi \varepsilon_0} \frac{\left(\frac{q}{2}\right)\left(\frac{3q}{4}\right)}{r^2}=\frac{3}{8}F$

Q5. A bob of heavy mass is suspended by a light string of length $l$. The bob is given a horizontal velocity $v_0$. If the string gets slack at some point, making an angle $\theta$ from the horizontal, the ratio of the speed of the bob at that point to its initial speed is

(a) $\left(\frac{\sin \theta}{2+3 \sin \theta}\right)^{1/2}$
(b) $(\sin \theta)^{1/2}$
(c) $\left(\frac{1}{2+3 \sin \theta}\right)^{1/2}$
(d) $\left(\frac{\cos \theta}{2+3 \sin \theta}\right)^{1/2}$

Correct answer: (d) $\left(\frac{\cos \theta}{2+3 \sin \theta}\right)^{1/2}$

Explanation:

Using energy conservation,

$v_0^2=v^2+2gl(1-\cos \theta)$

At slack condition,

$\frac{mv^2}{l}=mg \cos \theta \Rightarrow v^2=gl \cos \theta$

Substituting,

$v_0^2=gl(2+3 \sin \theta)$

So,

$\frac{v^2}{v_0^2}=\frac{\cos \theta}{2+3 \sin \theta}$

NEET 2027 Physics: Top 100 Questions Selection Method

Top 100 questions in NEET Physics have been chosen after analysing previous year’s NEET papers to pick out those concepts which are always asked in NEET. Rather than choosing questions at random, the top 100 questions focus on consistent themes, high-weightage chapters and numerical questions based on the pattern of NEET.

Top 100 questions in NEET Physics have been picked out according to the following criteria:

• Analysis of NEET Physics previous year question papers (PYQs).
• Coverage of high-weightage chapters on the basis of recent NEET paper analysis.
• Frequent concepts, formulas and numericals tested in NEET.
• Questions on conceptual, calculation, and application oriented aspects of Physics.
• Focus on NCERT level concepts of Physics and NEET Physics.

Can Top 100 Questions Alone Help You Score 150+ in NEET Physics?

There is no fixed set of questions which would result in a definite score in Physics. These Top 100 Questions should only be used as a revision aid. For scoring 150+ marks in NEET, one should also study the full syllabus along with revision of concepts through NCERT, chapter-wise PYQs, formula revision, mock tests, and error analysis.

The previous year's questions are very helpful in terms of identifying repeated concepts and question patterns, but should not be considered as a definite set of questions asked in the next NEET exam.
