NEET Physics Kinetic Energy Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): In an elastic collision between two particles, the total kinetic energy before and after the collision remains the same. | Reason (R): The kinetic energy of a neutron can decrease significantly in an elastic collision with a light nucleus like deuterium or carbon.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option B

Detailed Explanation

The assertion is true as the total kinetic energy is conserved in elastic collisions. The reason is also true but it explains a specific scenario of kinetic energy transfer, not the general principle of energy conservation in elastic collisions.
