Dear student,
Work done=F.d(dot product)
since F.d=Fd cos theta
and in circular path cos theta =0 theta being 90

Dear Debadrita,
Work done is zero in a circular path because the angle between force and displacement is zero.Centripetal force acts inwards on a body while displacement is along the tangent drawn on the circular path at that time.
