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.

A

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.

D

(d) If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Relative velocity of separation is equal to the relative velocity of approach. One of the case is shown below.

Before collision, relative speed is `2m//s` and relative velocity of approach is `6m//s`.
After collision, relative speed is `4m//s` and relative velocity of separation is `6m//s`.
