A small block of mass m is placed inside a hollow cone rotating about a vertical axis with angular velocity w as in the figure. The semivertical angle of the cone is q and the coefficient of friction between the cone and the block is m . If the block is to remain at a constant height h above the apex of the cone, what are the maximum and minimum values of w ?
