In the given diagram, the block of mass \( 2 \mathrm{~kg} \) and \( 3 \mathrm{~kg} \) are placed one over the other. The contact surface are rough with coefficient of friction \( \mu_{1}=0.2, \mu_{2}=0.06 \). A force
\( \mathrm{P} \)
\( F=\frac{1}{2} t \)
W
in the direction. (Given that \( g=10 \mathrm{~m} / \mathrm{s}^{2} \) )

Friction force acting between the two blocks at \( t=8 \mathrm{~s} \)
(1) \( 4 \mathrm{~N} \)
(2) \( 3 \mathrm{~N} \)
(3) \( 3.6 \mathrm{~N} \)
(4) \( 3.2 \mathrm{~N} \)
