Q 11-06-028NEETJEE MainMedium
A shell fired from a gun explodes in mid-air into several fragments. Ignoring air resistance, the centre of mass of the fragments
Answer: (B) continues along the original parabolic path
The explosion forces are internal, so they cannot change the motion of the centre of mass. The only external force is still gravity, so the centre of mass keeps following the same parabola (until a fragment hits the ground).
