Question

15. If two blocks of masses 3kg and 4kg are in contact. If we apply force 28N On
3kg. Reactional force on 3kg block from 4kg block is.​

Answer 1

Answer: 16N

Explanation:

When we apply 28 N force on 3 kg. The acceleration for both will be same i.e,

4 m/s^2. Now force on 4 kg due to this acceleration will be 16N.

So 4 kg will give equal and opposite reaction of 16N on 3 kg backward.

I hope you understand.
