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

A

Body C

B

Body B

C

Depends on height of breaking

D

Does not shift

Text Solution

Verified by Experts

The correct Answer is:
D
(d) No external horizontal force is applied, so `a_(cm) = 0` in horizontal direction. Also there is no velocity horizontal direction, so centre of mass does not shift compared to that of `A`.
