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 `mu=0.2` . The difference between the accelerations of the block, in case (B) and case (A) will be: `(g=10ms^(-2))`
