(C) Let the masses be $m_3 = 3 \ kg$,$m_2 = 2 \ kg$,and $m_1 = 1 \ kg$. The acceleration due to gravity is $g = 10 \ m/s^2$.$1$. Minimum force required for slipping to occur between $3 \ kg$ and $2 \ kg$ block:$F_{s1} = \mu_1 \cdot m_3 \cdot g = 0.5 	imes 3 	imes 10 = 15 \ N$.$2$. Minimum force required for slipping to occur between $2 \ kg$ and $1 \ kg$ block:$F_{s2} = \mu_2 \cdot (m_3 + m_2) \cdot g = 0.3 	imes (3 + 2) 	imes 10 = 0.3 	imes 50 = 15 \ N$.$3$. Minimum force required for slipping to occur between $1 \ kg$ block and ground:$F_{s3} = \mu_3 \cdot (m_3 + m_2 + m_1) \cdot g = 0.1 	imes (3 + 2 + 1) 	imes 10 = 0.1 	imes 60 = 6 \ N$.Since the minimum force required to initiate slipping is least for the surface between the $1 \ kg$ block and the ground $(6 \ N)$,slipping will start there first.

If force $F$ is increasing with time and at $t = 0, F = 0$,where will slipping first start?
