STATEMENT-l : 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-2 : In an elastic collision, the linear momentum of the system is conserved.

Options

A. If both, Assertion and Reason are true and Reason is correct explantion of Assertion.
B. If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both, Assertion and Reason are false.

Answer

D

Explanation

Here, Assertion is false, because in elastic collision the relative velocit of separation `(` not relative speed of separation `)` is equal to the relative velocity of approach `(` not relative speed of approach `)` of two bodies during collision . Hence reason is though true but cannot explain the Assertion. Hence false.
