MCQ
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
  • ✓
    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

Correct option: C.
Along the same parabolic path along which the intact shell was moving
c
By conservation of momentum, centre of mass moves on the same parabolic path.

A uniform metal chain of mass $m$ and length ' $L$ ' passes over a massless and frictionless pulley. It is released from rest with a part of its length ' $l$ ' is hanging on one side and rest of its length ' $L -l$ ' is hanging on the other side of the pulley. At a certain point of time, when $l=\frac{L}{x}$, the acceleration of the chain is $\frac{g}{2}$. The value of $x$ is ........
