A block of mass \( 5 \mathrm{~kg} \) is (i) pushed in case (A) and (ii) pulled in case (B), by a force \( F=20 \mathrm{~N} \), 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 \( \left(g=10 \mathrm{~ms}^{-2}\right) \)
(B) JEE (Main) 2019]
(a) \( 0.8 \mathrm{~ms}^{-2} \)
(b) \( 0{m s^{-2}}^{2} \)
(c) \( 3.2 \mathrm{~ms}^{-2} \)
(d) \( 0.4 \mathrm{~ms}^{-2} \)
