Question

# A ball of mass kg is attached to the end of a string having length 0.5 m. The ball is rotated on a horizontal circular path about vertical axis. The maximum tension that the string can bear is 324 N. The maximum possible value of angular velocity of ball (in rad/s) is

- 9
- 18
- 27
- 36

## The correct answer is: 36

### component will cancel

Component will provide necessary centripetal force the ball towards center *C.*
