Vedclass · Answer

(C) The work done $W$ is defined as the dot product of the force vector $\vec F$ and the displacement vector $\vec s$,given by $W = \vec F \cdot \vec s = Fs \cos 	heta$,where $	heta$ is the angle between the two vectors.Given that $W = 0$,$F 
eq 0$,and $s 
eq 0$,we have $Fs \cos 	heta = 0$.Since $F$ and $s$ are non-zero,it must be that $\cos 	heta = 0$.This implies $	heta = 90^\circ$ or $\pi/2$ radians.Therefore,the force vector $\vec F$ is perpendicular to the displacement vector $\vec s$.

Given that $W = \vec F \cdot \vec s = 0$ and $F \neq 0, s \neq 0$,then
