Given information
Given that the mass of the first block is and that of the block is They are connected by a rope over a pulley.
Step-by-step explanation
Step 1.
In case of the first block (A):
It is kept on a horizontal surface and therefore, the surface exerts an upward normal force on the block.
The force of gravity pulls the block in the downward direction .
Also, the cord connected to it on the right applies a tensional force on block A in the right direction due to the weight of the second block.
So, the free body diagram of the first block can be drawn as shown.
