Answer» s unbalanced force : unbalanced force is able to give motion to the body. because it acceleration the body in a specific direction by which body starts to move WITHOUT changing their SHAPE. (b) Y is balanced force : ACCORDING to Newton's 3rd law, “action and reaction are of equal in MAGNITUDE and directed in opposite directions. ” if two equal FORCES applied on a body are directed in opposites then body can't change its motion. but this force is able to change their shape. |
