Gravity and orbits

A satellite of mass m orbits Earth at a radius R and speed v, start subscript, 0, end subscript as shown below. An aerospace engineer decides to launch a second satellite that is double the mass into the same orbit. The mass of Earth is M.

What is the speed v of the heavier satellite in terms of v, start subscript, 0, end subscript?

(Choice A)
v, start subscript, 0, end subscript
(Choice B)
2, v, start subscript, 0, end subscript
(Choice C)
start fraction, v, start subscript, 0, end subscript, divided by, 2, end fraction
(Choice D)
start fraction, v, start subscript, 0, end subscript, divided by, square root of, 2, end square root, end fraction
