A uniform rod AB of mass m and length L ...

A uniform rod AB of mass m and length L rotates about a fixed vertical axis making a constant angle `theta` with it as shown in figure. The rod is rotated about this axis, so that point B the free end of the rod moves with a uniform speed `V` in the horizontal plane then the angular momentum of the rod about the axis is:

`1/(3)mvL sin theta`

`1/(4)mvL sin theta`

`mvL cos theta`

none of these
