A body A of mass M while falling vertically downwards under gravity breaks into two parts; a body B of mass 
M and, a body C of mass 
M. The centre of mass of bodies B and C taken together shifts compared to that of body A towards:
Text Solution
Verified by ExpertsB
Before breaking, the centre of mass of system is moving under gravity. Thus, acceleration of the centre of mass is gravitational acceleration. During breaking, internal forces come into play which are not responsible for the acceleration of the centre of mass.
This indicates that, the acceleration of centre of mass remains the same (equal to gravitational acceleration).
Thus, the centre of mass of system continues its original path.
