In the system show in figure, mass of the block placed on horizontal surface is M = 4 kg. A constant horizontal force of F = 40 N is applied on it as shown. The coefficient of friction between the blocks and surfaces is `mu = 0.5`. Calculate the values of mass m of the block on the incline for which the system does not move . `["sin" 37^(@) = (3)/(5), g = 10 m//s^(2)]`
