Question

The time period of a satellite moving in a circular orbit around a planet is independent of

• A. the mass of the planet.
• B. the radius of the planet.
• C. the mass of the satellite.
• D. all the three parameters.

Answer 1

The correct option is C the mass of the satellite.

The time period of satellite is given as$T=\frac{2\pi (R_e+h{)}^{\frac{3}{2}}}{\sqrt{G{M}_e}}$
where, T = time period of satellite
$M_e$= mass of the planet
$R_e$= radius of the planet
