STATEMENT If there is no external torque on a body about its centre of mass, then the velocity of the centre of mass remains constant.

Because

STATEMENT–2

The linear momentum of an isolated system remains constant

(A)  Statement–1 is True, Statement–2 is True; Statement–2 is a correct explanation for Statement–1

(B)  Statement–1 is True, Statement–2 is True; Statement–2 is NOT a correct explanation for Statement–1

(C)  Statement–1 is True, Statement–2 is False

(D) Statement–1 is False, Statement–2 is True

Best Answer

(D)       If external force acting on a body passes through centre of mass then torque acting on body about centre of mass is zero but velocity of centre of mass keeps on changing.
