A block of mass rests on a horizontal turntable rotating uniformly at ω rad/s. A string attacted to thin block passes through a hole in the centre of the table and supports another block of mass . The coefficient of static friction between the first block and the table is . Find the ratio of the maximum and minimum values of R for which the first block does not slide on the turn table [There is no friction between string & table] :-
