A block of mass 5 kg is (i) pushed in case [A] and (ii) pulled in case , by a force F = 20 N, making an angle of \[30{}^\text{o}\] 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 : \[(g=10m{{s}^{-2}})\] [JEE Main 12-4-2019 Afternoon]
