A small block with mass m is placed inside an inverted conethat is rotating about a vertical axis such that the time for onerevolution of the cone is T. the walls of the cone make an angle Bwith the vertical. The coefficient of static friction betweenthe block and the cone is ?. Draw a free body diagram.If the block is to remain a constant height h above the apex of thecone, what are the maximum and minimum values of T?
