A force of 5 N causes a displacement of 10 m in its direction. Calculate the work done by the force.
A force of 25 N25~ N25 N is applied at an angle of 60°60°60°in the direction of displacement. Calculate the amount of work done by the force if the displacement of the block is 5 m5~m5 m.
A force of 20 N acts on a body and displaces it 2m along the direction of force. Then the work done by the force is:
