Two blocks A and B of mass mA= 10 kg and mB = 20 kg are place on rough horizontal surface. The blocks are connected with a string. If the coefficient of friction between the block A and ground is μA = 0.9 and between block B and ground is μB = 0.3. Find the tension in the string in situation as shown in the figure below? Forces 120 N and 100 N start acting when the system is at rest.
