Final answer:
Satellite B would have the same orbital speed as Satellite A because this speed depends only on the mass of Earth and the orbit's radius, not on the satellites' masses. The principles governing satellite velocity apply uniformly regardless of the satellite's mass.
Step-by-step explanation:
The speed of Satellite B in orbit around Earth is determined by its orbital mechanics and is independent of the satellite's mass. Since it is placed in an orbit with the same radius as Satellite A, and they are both subjected to Earth's gravitational force, they would have the same orbital velocity. This is because orbital speed only depends on the mass of the Earth and the radius of the orbit, not on the mass of the satellite.
Let's utilize the concept from the question where two manned satellites are approaching each other with a relative speed intending to dock. This example illustrates how masses in space interact and are subject to gravitational forces. Although the masses given are different from those of Satellites A and B, the underlying principles that determine the satellite velocity remain the same.
