Question

Two blocks of mass 20kg and 30kg are connected by a light string and are present on a smooth horizontal plane. A force of 50N is acting on 30 kg block, then the force acting on the 20kg block is​

Answer 1

Explanation:

When the force 50 N is applied, the whole system will be accelerating. 

Let a be the acceleration of system as well as the acceleration of the blocks.

So, (20+30)a=50 or a=1m/s2
