A block of mass m is pulled by a constant power P placed on a rough horizontal plane. The friction coefficient between the block and the surface is `mu`. Maximum velocity of the block will be

A

`(p)/(mg)`

B

`(p)/(mu mg)`

C

`(mu p)/(mg)`

D

Infinite

Text Solution

Verified by Experts

The correct Answer is:
B
p = Fv
For maximum velocity
`f = f_(fr) = mu mg`
`v_(max) = (P)/(mu mg)`
