Vedclass · Answer

(C) Work done is defined by the formula $W = F \cdot s \cdot \cos(	heta)$,where $F$ is the force,$s$ is the displacement,and $	heta$ is the angle between them.When force and displacement are in mutually opposite directions,the angle $	heta$ is $180^o$.Since $\cos(180^o) = -1$,the work done becomes $W = -F \cdot s$,which is negative work.

In case of negative work,the angle between the force and displacement is: (in $^o$)
