Assertion: The velocity of a body at the bottom of an inclined plane of given height is more than when it slides down the plane, compared to, when it rolls down the same plane.
Reason: In rolling down, a body acquires, both kinetic energies of translational and rotational motions.

View answer and explanation

Correct option: B

If both assertion and reason are true but reason is not the correct explanation of the assertion

Option B (If both assertion and reason are true but reason is not the correct explanation of the assertion) is correct because both statements are true, but the reason doesn't directly explain why sliding is faster than rolling.
