Q.No.6.3:- Why fog droplets appear to the suspended in air?

Ans:-    Let suppose that the fog droplet is just like a small sphere. So when it flows through the air (which is fluid) then droplet will experience a retarding force of the magnitude 

As the droplet is very small so its radius is small and as a whole the drag force will be small. The drag force will be equal to its weight which is also very small. So the drop let will soon attains a terminal velocity which is
