Given information

From the above question it, it is given that 

Mass of block    

Mass of block  

Mass of block  

Acceleration,  

The net force on block  

The net force on block  

The net force on block  

Step-by-step explanation

Step 1.

For each block, the net force must be ma by Newton’s second law.

Each block has the same acceleration since the blocks are in contact with each other. 

Use the formula of net force,   

Where,  is the mass and  is the acceleration.

Understand that the net force on block   will be written as-For block ,
