Question # 1
When a gun is fired, it recoils.
- Ans 1: Total momentum o the gun and the bullet is zero before the firing. When gun fired, bullet moves in forward direction and gun recoils so theat total momentum after firing also becomes zero according to law of conservation of momentum.

Question # 1
Action and reaction are always equal and opposite. Then how does a body
Action and reaction are always equal and opposite. Then how does a body moves ?
-
Ans 1: Action and reaction are equal in magnitude but opposite in direction. Action and reaction do not act on the same body.
Action is applied on the body due to which an equal and opposite reaction is acting on another body. Both of these do notneutralize each other due to which the body will move.
