51. When a bullet is fired from a gun A.The gun moves forward B.The gun jumps up C.The gun does not move D.The gun recoils with the same momentum as the bullet
Option D Solution: When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
