Two blocks A and B of masses mA = 1 kg and mB = 3 kg are kept on the table as shown in figure. the coefficient of friction between A and B is 0.2 and between B and the surface of the table is also 0.2. The maximum force F that can be applied on B horizontally, so that the block A does not slide over the block B is : [Take g = 10 m/s2]
