A block of mass M is pulled along a horizontal surface by applying a force at angle `theta` with the horizontal. The friction coefficient between the block and the surface is `mu`. If the block travels at a uniform velocity, find the work done by this applied force during a displacement d of the block.

A

`(mu m gd)/(cos theta + mu sin theta)`

B

`(mu m gd cos theta)/(cos theta+ mu sin theta)`

C

`(mu m gd sin theta)/(cos theta + mu sin theta)`

D

`(mu g d cos theta)/(cos theta - mu sin theta)`
