# Should the speed of two artificial satellites of earth having different masses but the same orbital radius be the same?

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

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

From above relation, it is clear that the mass of a satellite has no effect on its its orbital velocity. If they have same orbital radius, then $R+h=r$ will also be same for them. Thus, the speed of the satellites should be same.
