Two artificial satellites, one close to the surface and the other away are revolving around the earth. Which has larger speed?

The orbital velocity of the artificial satellites revolving around the earth is,

\[v=\sqrt{\frac{GM}{R+h}}\;\;\text{or}\;\;v=R\sqrt{\frac{g}{R+h}}\]

A satellite which is close to the surface has less value of $h,$ so its orbital velocity will be more. Hence, the artificial satellite close to the surface of the earth has larger speed.
