Question

A body $A$ of mass $M$ while falling vertically downwards under gravity breaks into two parts; a body $B$ of mass $1/3M$ and a body $C$ of mass $2/3M$ . 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

The correct option is B does not shift

As the breaking phenomenon is a $result$ of internal forces so the center of mass will $still$ move in the same vertical direction.

So there will not be any shifting but the parts $B$ and $C$ will not be equidistant from the center line due to their unequal mass.
