Two objects which are initally at rest, ...

Two objects which are initally at rest, move towards each other under the action of their internal attraction. If their speeds are 4 v and 2 v at any instant, then the speed of centre of mass of the system will be

A

2v

B

zero

C

v

D

1.5v

Text Solution

Verified by Experts

The correct Answer is:
B
As initially both the particles were at rest, therefore, velocity of the center of mass were. Zero. And no external force acting on the system. So velocity remains constant (Zero).
