NEET Physics Kinetic Energy Assertion Reason Question
Assertion (A): In an elastic collision between two objects of equal mass, the magnitude of the velocity of each object after the collision is equal to the magnitude of the velocity of the other object before the collision.
Reason (R): In an elastic collision, both momentum and kinetic energy are conserved.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
In an elastic collision with equal masses, the velocities are exchanged due to both momentum and kinetic energy conservation, as shown in the NCERT context equations (5.23) and (5.24).
