The time period of a satellite in a circular orbit round a planet is independent of:
Correct answer: A. Mass of the satellite
- A. Mass of the satellite
- B. The radius of the planet
- C. The mass planet
- D. All of these
Explanation
The time period of a satellite does not depend on the mass of the satellite. According to Kepler's Third Law of Planetary Motion, the square of the orbital period (time period) of a satellite is directly proportional to the cube of the semi-major axis of its orbit. The mass of the satellite is not a factor in this relationship.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
