Question 2: Molarity changes with
(1) temperature
(2) pressure
(3) mass
(4) moles only

Correct Answer: (1)
Explanation: Volume changes with temperature, so molarity changes.

Question 3: Hybridisation of carbon in methane:
(1) sp
(2) sp2
(3) sp3
(4) sp³d

Correct Answer: (3)
Explanation: Methane has a tetrahedral geometry → sp³.

Question 4: Which of the following gives a positive Tollens test:
(1) acetone
(2) formaldehyde
(3) ether
(4) alkene

NEET Most Expected NCERT Questions with Answers – Physics

Physics remains one of the most challenging yet rank-defining sections in NEET. These carefully selected NCERT-based Physics questions focus on formula mastery, numerical accuracy, and repeated conceptual patterns to help aspirants avoid common mistakes and maximise marks.

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) 2v
(3) 22v
(4) 4v
Correct Answer: (3)
Explanation: Resultant momentum = 2mv², hence lighter fragment speed 22v.

Question: A spherical ball is dropped in a long column of viscous liquid. The speed vs time graph is the following:
(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. The magnetic field at the centre is the following:
(1) 6.28×10−4T
(2) 6.28×10−2T
(3) 12.56×10−4T
(4) 12.56×10−2T
Correct Answer: (3)
Explanation: B=μ₀nI=4π×10⁻⁷×1000×1=12.56×10⁻⁴T.

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) 1:2
(2) 2:1
(3) 2:1
(4) 1:2
Correct Answer: (2)
Explanation: kcenter=R² and ktangent=R, a ratio of 2:1.

Question: If a nucleus of mass number 189 splits into two nuclei of mass numbers 125 and 64, the ratio of radii is
(1) 25:16
(2) 5:4
(3) 4:5
(4) 1:1
Correct Answer: (2)
Explanation: Nuclear radius R=R₀A¹/³, so the ratio 125¹/³:64¹/³=5:4.
