Question # 1

Action and reaction are always equal and opposite

Ans 1: Action and reaction are equal in magnitude but opposite in direction Action and reactioin do not act on the same body Action is applied on one body due to which an equal and opposite reaction is action on another body. Both of these do not neutralize each other due to which the body will move
