Throughout the circular path there at infinitely many points through which the object travels. So at every point the object will be tangential to the core or the centre of the circular path. So the angle will be 90 degrees. Now, Work done = Force*displacement* cos theta Here theta = 90 But cos 90 =

So the angle will be 90 degrees.
Now,
Work done = Force*displacement* cos theta
Here theta = 90
But cos 90 =
So work done = F*s*0
= 0 joules
So the work done will be 0.
