No,
> if force is applied on a body and body doesn't show any displacement then work done is said to be zero
=>When we puss wall we apply force but there is no displacement in the wall so according to formula of work done
work done=FS
work done=F×0
work done=0
> If force is applied on a body is perpendicular to the displacement Then work done is equal to zero.
=>A man carrying load on his head standing at a place.
here,work done=FS costheta
cos90=0
so,work done in this case will also be zero.
