A block of mass m is pulled along a horizontal surface by applying a force at an angle `theta`, with the horizontal. If the block k travels with a uniform velocity and has a displacement d and the coefficient of friction is `mu`. Then find the workdone by the applied force?

A

`(mu mgd)/((cos theta+mu sin theta))`

B

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

C

`(mu mg d sin theta)/((cos theta+mu sin theta))`

D

`(mu mg d cos theta)/((cos theta+mu sin theta))`
