what happens to the work done when teh displacement of a body is at right angles to the direction of force acting on it? Explain the detail
Work done (W) by a force (F) in displacing a body through S is given by,
W = (F)(S) cosθ
Where, θ is the angle between F and S.
When force is perpendicular to displacement, θ = 90o and cos90 = 0
So, work done = 0
