Question

Two blocks of mass 8 kg and 4 kg are placed side by side on a smooth horizontal surface. A horizontal force of 40 N is applied on 4 kg block then what is the normal reaction between the two blocks ?​

Answer 1

Explanation:

the normal reaction force exerted by the 8 kg block on the 4 kg block is 40 N.

This is because the force exerted by a normal reaction force is always equal to the force applied.(Only in the absence of friction or any resisting force.)

Hope it helps
