The block shown is moving with constant velocity. Find `mu_(k)` between the block and the surface.

A

`tan theta`

B

`cot theta`

C

`sin theta`

D

`cos theta`

Text Solution

Verified by Experts

The correct Answer is:
a
Since the velocity of the block is constant, net force parallel to the incline is zero
`rarrm g sin theta = mu_(k)N=mu_(k)(m g cos theta) rarr tan theta =mu_(k)`
