In the mathematical relationship governing orbital velocity ($v = ext{sqrt(GM/r)}$), which factor is dominant?

Answer

The distance from the Earth's center of mass ($r$)

The inverse-square law of gravity means that the distance ($r$) between the orbiting body and the center of mass of the body being orbited is the dominant variable in determining the necessary orbital velocity.
