Two balls of mass m and 4m are connected...

Two balls of mass m and 4m are connected by a rod of length L. The mass of the rod is small and can be treated as zero . The size of the balls also can of the neglected . We also assume the centre of the rod is hinged ,but the rod can rotate about its centre in the vertical plane without friction . What is the gravity - induced angular acceleration of the rod when the angle between the rod and the vertical is `theta` as shown ?

A

`(5g)/(6L)sintheta`

B

`(g)/(6L)costheta`

C

`(6g)/(5L)sintheta`
