Two blocks are connected by a spring and given velocity `v_(1)` and `v_(2)` as shown in figure when spring is unstrected

Statement-1: In centre of mass frame, both the blocks come to rest simultaneously
Statement-2: Momentum of a system in centre of mass frame is always zero.

A

Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.

B

Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.

C

Statement-1 is true, statement-2 is false.

D

Statement -1 is false, statement -2 is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Momentum of a system is zero in C-frame so if 2 block system is true and one comes to rest w.r.t.c.m. other will also be at rest to make momentum zero
