A block of mass M is situated on a smooth horizontal table. A thread tied to the block passes through a hole in the table and carries a mass m at its other end. If the length of thread above the table is l and M is revolving in horizontal circle with angular speed ω ω on the table, then value of m so that it remains suspended at a constant height h is –
