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 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.
