(a) When force is at an angle θ to the direction of displacement, then work done, W= F S cos θ

(b) (i) For zero work done, the angle between force and displacement should be 90o as cos 90o = 0

W = FS cos90o= FS x 0 = 0

(ii) For maximum work done, the angle between force and displacement should be 0o as cos0o = 1

Hence, W=FScos 0o=FS
