two blocks of masses 2 kg and 3 kg are placed on a plank. an external force of 10n is acting on 2 kg block and the whole system including the plank is moving vertically up with a constant acceleration a0 = 2 m/s2 . the normal reaction force between the 3 kg block and plank is : (g = 10 m/s2 )

Two blocks are placed in contact on a smooth horizontal surface. Their masses are 2 kg and 3 kg. A 100 N force pushes on the 2 kg block. What is the magnitude of the force that the 2 kg block exerts on the 3 kg block?
Suppose force F is applied on mass m1 (=2kg) which is in contact with the mass m2 (=3kg).If the normal reaction ‘R’applied by mass ‘m1′ on mass’ m2′ and vice versa. Then for mass ‘my we have
F—R=m1 a
R=m2 a
F=(m1+m2)a
a=F/(m1+m2)=100/(2+3)
=20m/s^2
Reaction between the two blocks, R=m2 a
=(3×20) N
=60 N
