Question

The time period of an artificial satellite in a circular orbit is independent of

• A. the mass of the satellite
• B. radius of the orbit
• C. mass of the earth and radius of the earth
• D. None of the above

Answer 1

Answer: (A)

the mass of the satellite

Answer 2

The time period of an artificial satellite is given by $T=2 \pi \sqrt{\frac{\left(R_{e}+h\right)^{3}}{g R_{e}^{2}}}$ where $R_{e}$ is radius of earth and $h$ the height of satellite. From the above formula it is clear that time period of revolution does not depend upon the mass of the satellite.
