In the figure shown if coefficient of friction is `mu`, then `m_(2)` will start moving upwards if

A

`(m_(1))/(m_(2)) gt sin theta - mu cos theta`

B

`(m_(1))/(m_(2)) gt sin theta + mu cos theta`

C

`(m_(1))/(m_(2)) gt mu sin theta - cos theta`

D

`(m_(1))/(m_(2)) gt mu sin theta + cos theta`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `m_(1)g gt m_(2)g sin theta+mum_(2)g cos theta`
`implies" " (m_(1))/(m_(2))gt sin theta+ mu cos theta`

A uniform ring of mass m is placed on a rough horizontal fixed surface as shown in the figure. The coefficient of friction between the left part of the ring and left part of the horizontal surface is mu_(1)=0.6pi and between right half and the surface is mu_(2)=0.2pi . At the instant shown, now the ring has been imparted an angular velocity in clockwise sense in the figure shown. At this moment magnitude of acceleration of centre O of the ring (in m//s^(2) ) is (take g=10m//s^(2) )
