Question

If a satellite is revolving very close to the surface of earth, then its orbital velocity does not depend upon.

• A. mass of satellite
• B. mass of earth
• C. radius of earth
• D. orbital radius

Answer 1

The correct option is A mass of satellite

Orbital velocity, $v=\sqrt{\frac{GM}{r}}$ where $r$ is the orbital radius and $M$ is the mass of earth.

Thus, $v$ is independent of mass of satellite(m).
