Assertion: If there is no external torque on a body
\( \mathrm{P} \)
about its center of mass, then the velocity of the center of mass remains AAt onstant.
Reason: The linear momentum of an isolated system remains constant.
(1) Assertion is True, Reason is True; Reason is correct explanation for Assertion
(2) Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(3) Assertion is True, Reason is False
(4) Assertion is False, Reason is True
