Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion $(A)$ : In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision.

Reason $(R)$ : In an elastic collision, the linear momentum of the system is conserved.

In the light of the above statements, choose the correct answer from the options given below

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

Answer 1

Answer: (D)

If both Assertion and Reason are false.

Answer 2

Assertion is false and reason is true because for $e = 1$, velocity of separation equals the velocity of approach but these are not relative manner.
