Two identical small balls are suspended ...

Two identical small balls are suspended by ends of a rod. Whole assembly is rotating about vertical axis passing through center of rod. At a certain value of `omega` both strings make 37° with vertical. Find `omega`

A

`sqrt((2)/(3))` rad/sec

B

`sqrt((7)/(3))` rad/sec

C

`sqrt((3)/(2))` rad/sec

D

`sqrt((5)/(2))` rad/sec

Text Solution

Verified by Experts

The correct Answer is:
C

`T cos theta=mg`
`T sin theta=m omega^(2)r`
`tan theta=(omega^(2)5)/(g)`
`omega=sqrt((3)/(2))`rad/sec
