A body moves along a circular path of radius 10m and the coefficient of friction is 0.5.What should be its angular speed `(in rad s^(-1))`, if is not to slip from the surface ? `(Given,g =9.8ms^(-2))`

A

5

B

10

C

`0.1`

D

`0.7`

Text Solution

Verified by Experts

The correct Answer is:
D
`omega = sqrt((mu g)/( r))`
`omega = sqrt((0.5 xx 10)/(10)) = 0.7` rad/sec
