Question

2 blocks of masses m1=10kg and m2=5kg connected to each other by a massless in extensible string of length 0.3m and placed along the diameter of a turn table coefficient of friction=0.5 between surface of table and m1 and there is no friction between table and m2.the table is rotating with 10rad/s about the vertical axis.the mass m1 is at a distance of 0.124m from centre.1)if the masses are at rest,calculate the frictional force on m1.2)what should be the angular speed of table if the masses just start to slip?
