A block of mass m is placed at the top of a smooth wedge A B C . The wedge is rotated about an axis passing through C as shown in the figure. The minimum value of angular speed ω such that the block does not slip on the wedge is-, ( g sin θ l ) sec θ, ( g l ) cos θ, ( g l cos θ ) cos θ, g sin θ l a
