Question

Two blocks A and B of masses 4 kg and 12 kg are
placed on a smooth horizontal surface. A force of
magnitude 80 N is applied on A as shown in the
figure. The contact force between A and B is

(1)90 N
(3)30
(2) 25 N
(4) 60N​

Answer 1

Explanation:

what is thermodynamics?

Answer 2

Answer:

(4) 60N

Explanation:

Fc=(M2xF)/(M1+M2)

Fc=(12x80)/(4+12)

Fc=(12x80)/16

Fc=12x5

Fc=60N
