Statement I: In an elastic collision bet...

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.

A

Both Statement I and Statement II are true and Statement II is the correct explanation of Statement I

B

Both Statement I and Statement II are true but Statement II is not the correct explanation of Statement I.

C

Statement I is true and Statement II is false.

D

Statement I is false and Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
D
In case of elastic collision coefficient of restitutin `e=1`.
Magnitude of relative velocity of approach`=` Magnitude of relative velocity of separation. But relative speed of approach `!=` relative speed of separation.
