Two satellites A and B move around earth in a circular orbit

[Yatin]

Two satellites A and B move around Earth in a circular orbit. The mass of B is twice the mass of A then
I agree that kinetic energy of B is greater than that of A. But what I couldn't understand was that why are speeds of A and B equal as given in the book.
Shouldn't they differ according to the formula: orbital velocity =(GM/R)^1/2

M is the mass of the Earth, not the satellite.

Thanks I got it.
