The time period of an earth satellite in circular orbit is independent of

Options

A. both the mass and radius of the orbit
B. neither the mass of the satellite nor the radius of its orbit
C. the mass of the satellite
D. radius of its orbit

Answer

C

Explanation

The periodic of an earth's satellite is given by
`T = 2pi sqrt(((R+h)^(3))/(GM))`
where M and R denote the mass and the radius of the earth. Thus T is independent of the mass of the satellite.
