SUMMARY
The discussion clarifies that a more massive communications satellite does not orbit more slowly than a smaller one due to the balance of gravitational force and mass. Both satellites experience the same gravitational acceleration when at the same orbital distance from Earth. The centripetal force required for circular motion is provided by gravity, and according to Kepler's laws, the orbital period is independent of the satellite's mass. Thus, both satellites maintain the same orbital speed when positioned at equal distances from the planet.
