Question

When a shell in motion suddenly explodes in mid air the centre of mass of the fragments moves

• A. Vertically downwards
• B. Horizontally
• C. In the same parabolic path as if the shell were unexploded
• D. Vertically upwards

Answer 1

The correct option is C

In the same parabolic path as if the shell were unexploded

Internal forces do not effect the motion of centre of mass. So, centre of mass moves in the same parabolic path as if the shell were unexploded.
