17. When is work zero ? A force of 40 N is applied to a body. If the line of action of the force
makes an angle of 45° with the direction of the displacement of the body, then calculate the
amount of work done, when the body is displaced by 2 m.

Answer:
when net displacement is zero then work is zero
W= F.S= 40×2×Cos45°=40√2

Answer:
when the net displacement is zero, the work is zero.
W=FS cos theta.
w=40*2*cos45°
therefore, w=40√2.
