Vedclass · Answer

(D) The motion of the centre of mass of a system depends only on the external forces acting on it. In this case,the only external force acting on the body $A$ (and subsequently on the system of parts $B$ and $C$) is the gravitational force,which results in an acceleration equal to $g$ downwards. Since the external force remains unchanged during the breaking process,the acceleration of the centre of mass remains $g$. Therefore,the trajectory of the centre of mass of the system consisting of parts $B$ and $C$ follows the same path as the original body $A$. Thus,the centre of mass does not shift relative to the path of the original body $A$.

$A$ body $A$ of mass $M$ while falling vertically downwards under gravity breaks into two parts; a body $B$ of mass $\frac{2}{3} M$ and a body $C$ of mass $\frac{1}{3} M$. The centre of mass of bodies $B$ and $C$ taken together shifts compared to that of body $A$ towards
