Question
Two artificial satellites, one close to the surface and the other away are revolving around the earth. Which has larger speed?
Solution
The relation for orbital velocity , v = 
where,
h is the height of the satellite above the Earth's surface.
It is evident from the above formula that, smaller the value of h, greater is the value of v and vice versa.
Therefore, the satellite which is revolving close to the earth has larger speed.
