A block of mass m is being pulled up the rough incline , inclined at angle `theta` with horizontal by an agent delivering constant power P. The coefficient of friction between block & incline is `mu`. Then during the upward motion along the inclined plane , maximum velocity of the block will be :

A

`(P)/("mg" sin theta + mu " mg"cos theta)`

B

`(P)/("mg" sin theta - mu " mg"cos theta)`

C

`(P)/("mg" sin theta)`
