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

Options

A. the mass of the satellite
B. radius of the orbit
C. none of these
D. both of these

Answer

A

Explanation

Time period of an earth satellite is given by
`T^(2)=(4pi^(2))/(GM_(E ))(R_(E )+h)^(3)`
or `T=2pi(R_(E)+h)^(3//2)/sqrt(GM_(E))`
hence time period is independent of mass of the satellite
