Two blocks A and B having masses 100 kg ...

Two blocks A and B having masses 100 kg and 200 kg are placed as shown in the figure. The block A is connected to a wall with a light inextensible string. The coefficient of friction between the blocks is 0.3 and that between the block B and the floor is 0.03. Then the minimum force required to move the block B will be (take `g=10m//s^(2)`)
