NCERT Physics Questions for NEET Exam Practice

Physics in NEET 2026 demands accuracy and speed. Most scoring problems are direct NCERT physics-based questions. Practising these MCQs helps students master important physics formulas, laws, and numerical applications. It also builds confidence and accuracy for the final day of the NEET 2026 exam.

Here are some NCERT- Based Physics MCQs:

Question: A shell initially at rest explodes into three fragments of masses in the ratio $2:2:1$. The two heavier fragments move perpendicular to each other with equal speed $v$. The speed of the lighter fragment is:
(1) $v$
(2) $\sqrt2 v$
(3) $2\sqrt2 v$
(4) $4v$
Correct Answer: (3)
Explanation: Resultant momentum $=2mv\sqrt2$, hence lighter fragment speed $2\sqrt2 v$.

Question: A spherical ball is dropped in a long column of viscous liquid. The speed vs time graph is:
(1) Decreasing
(2) Increasing then constant
(3) Constant
(4) Linear increase
Correct Answer: (2)
Explanation: Velocity increases until terminal velocity, then becomes constant.

Question: A long solenoid having $1000$ turns per metre carries a current of $1A$. Magnetic field at the centre is:
(1) $6.28\times10^{-4}T$
(2) $6.28\times10^{-2}T$
(3) $12.56\times10^{-4}T$
(4) $12.56\times10^{-2}T$
Correct Answer: (3)
Explanation: $B=\mu_0 nI=4\pi\times10^{-7}\times1000\times1=12.56\times10^{-4}T$.

Question: The ratio of the radius of gyration of a uniform disc about an axis through its centre perpendicular to the plane and about a tangent in the plane is:
(1) $1:\sqrt2$
(2) $\sqrt2:1$
(3) $2:1$
(4) $1:2$
Correct Answer: (2)
Explanation: $k_{center}=\dfrac{R}{\sqrt2}$ and $k_{tangent}=R$ ratio $\sqrt2:1$.

Question: If a nucleus of mass number $189$ splits into two nuclei of mass numbers $125$ and $64$ ratio of radii is:
(1) $25:16$
(2) $5:4$
(3) $4:5$
(4) $1:1$
Correct Answer: (2)
Explanation: Nuclear radius $R=R_0 A^{1/3}$ so ratio $125^{1/3}:64^{1/3}=5:4$.
