Statement I: In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision.
Statement II: In an elastic collision, the linear momentum of the system is conserved.

Options

A. Statement-I is True, Statement-II is True and Statement-II is a correct explanation for Statement-I.
B. Statement-I is True, Statement-II is True and Statement-II is NOT a correct explanation for Statement-I.
C. Statement-I is True, Statement-II is False.
D. Statement-I is False, Statement-II is True

Answer

B

Explanation

In case of elastic collision, coefficient of restitution, e = 1.
Magnitude of relative velocity of approach = Magnitude of relative velocity of separation.
