The blocks are connected with a string. If the coefficient of friction between block A and ground is μ A ​ =0.9 and between block B and ground is μ B ​ =0.3, find the tension in the string in situation as shown in Fig. Forces 120N and 100N start acting when system is at rest?

then determine the minimum and maximum values of mass of block m to keep the heavy block M stationary. Two blocks M and m are arranged as shown in Fig. If M = 50 kg
