A block of mass 5 kg is (i) pushed in case (A) and (ii) pulled in case (B), by a force $\mathrm { F } = 20 \mathrm {~N}$, 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 of the block, in case ( B ) and case ( A ) will be: ( $\mathrm { g } = 10 \mathrm {~m} \mathrm {~s} ^ { - 2 }$ ) (1) $3.2 \mathrm {~m} \mathrm {~s} ^ { - 2 }$ (2) $0 \mathrm {~m} \mathrm {~s} ^ { - 2 }$ (3) $0.8 \mathrm {~m} \mathrm {~s} ^ { - 2 }$ (4) $0.4 \mathrm {~m} \mathrm {~s} ^ { - 2 }$
