Vedclass · Answer

(A) When a body moves on a rough horizontal plane with uniform velocity,the net force acting on it is zero. This implies that the applied force is equal in magnitude and opposite in direction to the frictional force. The work done by the applied force is positive because the applied force acts in the direction of the displacement of the body. Conversely,the work done by the frictional force is negative because it acts opposite to the direction of displacement.

Justify,giving proper reasoning,whether the work done in the following case is positive or negative: Work done by an applied force on a body moving on a rough horizontal plane with uniform velocity.
