Question

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

• A. depends on height of breaking
• B. does not shift
• C. body $C$
• D. body $B$

Answer 1

Answer: (B)

does not shift

Answer 2

Since, the acceleration of centre of mass in both the cases is same equal to g. So the centre of mass of the bodies $B$ and $C$ taken together does not shift compared to that of body $A$.
