Question

A shell fired from a gun at an angle to the horizontal explodes in mid air. Then the centre of mass of the shell fragments will move

• A. vertically down
• B. horizontally
• C. along the same parabolic path along which the 'intact' shell was moving
• D. along the tangent to the parabolic path of the 'intact' shell, at the point of explosion.

Answer 1

The correct option is C along the same parabolic path along which the 'intact' shell was moving

Since in the explosion there was no external force which acted

so, the movement of centre of mass will not be affected.
