Work done in a circular path is zero as we know work done=force cosx ×displacement and since the angle made by the force with displacement is 90° and we know cos 90°=0 so work done in a complete or half or 3/4th ....etc are all 0...hope u like it..but dont give me brainleist

give reason
reason is cos 90° because we know work done = force ×cos theta × displacement
and since in circular path force vector makes 90° with displacement
so work done =0
