A block is kept on a inclined plane of inclination `theta` of length l. The velocity of particle at the bottom of inclined is (the coefficient of friction is `mu`

A

`sqrt(2 gl (mu cos theta - sin theta))`

B

`sqrt(2 gl (sin theta - mu cos theta))`

C

`sqrt(2 gl (sin theta + mu cos theta))`

D

`sqrt(2 gl (cos theta - mu sin theta))`

Text Solution

Verified by Experts

The correct Answer is:
B
`v^(2) = U^(2) + 2as implies V= sqrt(o^(2) + 2g (sin theta - mu cos theta)l)`
