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

`Tcos theta=mg`
`Tsin theta =momega^(2)r`
`tan theta=(omega^(2)5)/(g)`
`omega=sqrt((3)/(2))" rad/sec"`
