The moment of inertia of a rod about an ...

The moment of inertia of a rod about an axis through its centre and perpendicular to it, is `(1)/(12)ML^(2)` (where, M is the mass and L is length of the rod). The rod is bent in the middle, so that two halves make an angle of `60^(@)`. The moment of inertia of the bent rod about the same axis would be

A

`1/(48)ML^2`

B

`1/12 ML^2`

C

`1/(24) ML^2`

D

`(ML^3)/(8sqrt3)`
