A uniform rod of mass `m=1.5 kg` suspended by two identical threads `l=90 cm` in length ( figure ) was turned through a small angle about the vertical axis passing through its middle point `C`. The threads deviated in the process through an angle `alpha=5.0^(@)`. Then the rod was released to start performing small oscillations.
Find`:`
`(a)` the oscillation period,
(b) the rod's oscillation energy.

A

`T=2pi sqrt((l)/(3g))`

B

`T=2pi sqrt((l)/(g))`

C

`T=2pi sqrt((3l)/(g))`

D

None of these
