True

Vedclass · Answer

(A) The work done $(W)$ is given by the formula $W = Fs \cos 	heta$,where $F$ is the force,$s$ is the displacement,and $	heta$ is the angle between the force and displacement vectors.When $	heta = 90^{\circ}$,$\cos 90^{\circ} = 0$.Therefore,$W = Fs 	imes 0 = 0$.Since the work done can be positive,negative,or zero,the minimum value of work done (in terms of magnitude) occurs when the force is perpendicular to the displacement,resulting in zero work.

State whether the following statement is true or false:
In order to get minimum work,the angle between force and displacement should be $90^{\circ}$.
