A uniform solid bar of wood floats vertically in water with 10 cm of its height immersed in the water. When it is slightly depressed and released, it oscillates with a frequency of

A

`(pi)/(7) Hz`

B

`(sqrt(2 pi ))/(7) Hz`

C

`(7)/(pi) Hz`

D

`(7)/(sqrt(2 pi )) Hz`

Text Solution

Verified by Experts

The correct Answer is:
D
`f=(1)/(2pi)sqrt((g)/(d))=(1)/(2pi)sqrt((9.8)/(0.1))=(1)/(2pi)(7sqrt(2))`
