For the situation shown in figure, mark the correct options.
(a) At \( t=3 \mathrm{~s} \), pseudo force on \( 4 \mathrm{~kg} \) block applied from \( 2 \mathrm{~kg} \) is \( 4 \mathrm{~N} \) in forward direction
(b) At \( t=3 \mathrm{~s} \), pseudo force on \( 2 \mathrm{~kg} \) block applied from \( 4 \mathrm{~kg} \) is \( 2 \mathrm{~N} \) in backward direction
(c) Pseudo force does not make an equal and opposite pairs
Smooth
(d) Pseudo force also makes a pair of equal and opposite forces
