A body A of mass M while falling wertically downwards under gravity brakes into two parts, a body B of mass `(1)/(3)` M and a body C of mass `(2)/(3)` M. The center of mass of bodies B and C taken together shifts compared to that of body A towards

Text Solution

Verified by Experts

The centre of mass of `B` and `C` does not shift compared to the centre of mass of `A`. It continues to move vertically downwards under gravity. This is because no new external force is involved in this case.
