AB is a quarter of smooth circular track of radius `R=6m`. A particle P of mass `0.5kg` moves along the track from A to B under the action of the following forces.

a. A force `F_1` directed always towards the point B, its magnitude is constant and is equal to `20N`.
b. A force `F_2` directed along the instantaneous tangent to the circular track, its magnitude is `(15-10S)N`, where S is the distance travelled in metre.
c. A horizontal force of magnitude `30N`.
Find the work done by forces mentioned in (a), (b) and (c)
