A block of mass 5 kg is (i) pushed in case (A) and (ii) pulled in case (B), by a force\[F=20\text{ }N\], making an angle of \[30{}^\circ \] 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 (in \[m/{{s}^{2}}\]) of the block, in case (B) and case (A) will be: \[(g=10m{{s}^{-2}})\]            

Answer:

0.8
