A block of mass $\displaystyle 5$ kg is (i) pushed in case (A) and (ii) pulled in case (B), by a force $\displaystyle \mathrm{F}=20 \mathrm{~N}$, making an angle of $\displaystyle 30$° with the horizontal, as shown in the figures. The coefficient of friction between the block and floor is $\displaystyle \mu=0.2$. The difference between the accelerations of the block, in case (B) and case (A) will be : $\displaystyle \left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$
