Plz clarify.

But Priyanka,the fan has been 'suspended'.
Moreover, what about gravity?

According to newton's 3rd law, there is the chain is pulling the ceiling with force F and the ceiling is pulling the chain with -F

The chain is pulling the ceiling and the ceiling is pulling the chain, otherwise the chain would fall to the ground.
Imagine you are the ceiling, you would have to pull the chain with a force = chain weight + object weight. With this force, the objects remain still.
If you pull it with a larger force, the objects will be moving upwards; if you pull it with a weaker force, the objects will move downwards.
It is action and reaction.

for every action there is an equal and opposite reaction.so if chain pulls the ceiling with a force F then ceiling must also pull the chain with same force F.

What you have here is a beam problem. In structures in volving beams forces are solved in terms of ernergy formula and aplying Newton's 3rd law which basically means that the sum of the weight on the beam is equal to the sum of the reactions.

Every action has an equal and opposite reaction.
