Two blocks A = 100 N and B = 150 N are resting on ground as shown in Fig. 8.13. Coefficient of friction between ground and block B is 0.10 and that between block B and A is 0.30. Find the minimum value of weight P in the pan so that motion starts. Find whether B is stationary w.r.t. ground and A moves or B is stationary w.r.t. A.
