A block of mass m is placed at the top of a smooth wedge ABC. The wedge is rotated about an axis passing through C as shown in the figure - 3.81. The minimum value of angular speed `omega` such that the block does not slip on the wedge is :

`(sqrt((gsin theta)/(l)))sec theta`

`(sqrt((g)/(l)))cos theta`

`(sqrt((g)/(l cos theta)))cos theta`

`sqrt((g sin theta)/(l))a`
