A wheel having moment of inertia `2 kg m^(2)` about its vertical axis, rotates at the rate of `60 rpm` about this axis. The torque which can stop the wheel's rotation in one minute would be

A

`(pi)/(12)Nm`

B

`(pi)/(15)Nm`

C

`(2pi)/(15)Nm`

D

`(pi)/(18)Nm`

Text Solution

Verified by Experts

The correct Answer is:
B
`tau=(I(omega_(2)-omega_(1)))/(t)=(Ixx2pi(n_(2)-n_(1)))/(t)=(pi)/(15)Nm`
