Statement-1: if there is no external torque on a body about its centre of mass, then the velocity of the center of mass remains constant.
Statement-2: The linear momentum of an isolated system remains constant.

Text Solution

Verified by Experts

The correct Answer is:
D
For statement-1: Force may be acting through centre of mass as shown in figure. For this, torque about CM will be zero. The force F will produce an acceleration in the CM.
