As we learn

Dependence of Orbital velocity -

Depends upon the mass of the central body and radius of orbit

Greater the value of radius of orbit, less be the orbital velocity

- wherein

V\: \alpha \: \frac{1}{\sqrt{r}}

r\rightarrow radius of earth

Independent of mass of orbiting body

 

 V = \sqrt{\frac{GM}{r}}

Here m = mass of the earth

Orbital velocity does not depend on the mass of the satellite.

Hence VA : VB = 1:1
