if both blocks move together, it is obvious that 8N will act on the lower block, which is more than the limiting friction of

4n(g =10m/s2), acceleration of upper block =(12-F)/2 = (12-4)/2 = 4m/s2, lower block =F/4 =4/4 =1m/s2

From the momentum Conservation, m1v + 0 = (m1+m2)v’ v’ = m1v/(m1+m2) m/s. J = change in momentum ( for second object.) that is = > Pf – Pi => (m2)v’ - m2*0 => m1*m2*v/(m1+m2) N-m.
