Two blocks of masses m1 = 4 kg and m2 = 6 kg are standing one on the top of the other,
as shown in the figure. The coefficients of static and kinetic friction between the blocks are
µs = 0.3 and µk = 0.2 respectively. The surface between m2 and the floor is frictionless. A
horizontal force F is applied on the m1 as shown in the figure. (g = 10 m/s2
)
