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

Options

A. `(p)/(mg)`
B. `(mu p)/(mg)`
C. `(p)/(mu mg)`
D. `(p)/(N^(2)//mg)`

Answer

C

Explanation

A block of ……………
`FV = P`
`v = (P)/(F)`
foe max velocity `F` should be mminimum which is equal to `mu mg` just to drag the block `v_(max) = (P)/(mu mg)`
