A string of length `0.1` m cannot bear a tension more than 100 N. It is lied to a body of mass 100 g and rotated in a horizontal circle. The maximum angular velocity can be

A

`100"rad s"^(-1)`

B

`1000"rad s"^(-1)`

C

`10000s^(-1)`

D

`0.1"rad s"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`T=100N=momega_(m)^(2)r`
`rArr" "100=100xx10^(-3)xx omega_(m)^(2)xx0.1`
`rArr" "omega_(m)=100rads^(-1)`
