A block of mass 5 kg is (i) pushed in case (A) and (ii) pulled in case (B), by a force F = 20 N, making an angle of 30^∘ with the horizontal, as shown in the figures. The coefficient of friction between the block and floor is μ=0.2 . The difference between the accelerations of the block, in case (B) and case (A) will be: (g=10ms^−2)

Two blocks A and B of masses mA=1kg and mB=3kg 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=10m/s^2]
