Question

give reason greater the displacement , more is the work done

Answer 1

Answer :-

Work done = Force ∗ displacement i.e W = F.x Cosθ where θ is the displacement angle

W = F. Cos 90 = 0 (Since Cos 90 degree is equal to zero)

Hence when the force applied and displacement of the body are inclined at 90 degree's with each other work done is zero.
