Vedclass · Answer

(D) The work done $(W)$ by a force $(F)$ on a body is given by the formula $W = F \cdot s \cdot \cos(	heta)$,where $s$ is the displacement and $	heta$ is the angle between the force and the displacement.For the work done to be positive,$\cos(	heta)$ must be positive,which occurs when $0^\circ \le 	heta This means the body must move in the same direction as the applied force (or at an acute angle to it).Therefore,if the body moves along the direction of the applied force,the work done is positive.

The work done by a force on a body will be positive if the:
