The time period of a satellite moving in a circular orbit around a planet is independent of : |
the mass of the satellite. the mass of the planet. the radius of the planet. all the three parameters. |
the mass of the satellite. |
Time period in terms of orbital speed is given by : T = 2πr/vo = 2πr/√(GM/r) = 2π√(r3/GM) where, T = time period of satellite M = mass of the planet r = radius of the orbit of the satellite From the above equation, we can see that T depends on radius of the orbit and the mass (density) of the planet but not the mass of the satellite. |
