What is the period of revolution of a satellite of mass m that orbits the earth in a circular path of radius $7880 \; km$ about $1500 \; km$ above the surface of the earth?
Given,
Radius of the orbit $(r) = 7880\;km = 7880\; * \;10^3\;m$
Height $(h) = 1500\;km = 1500\;*\;10^3\;m$
Period of revolution $(T) = \;?$
Radius of earth $(R) = r - h = (7880 - 1500)\; * \; 6380\;*\;10^3\;m$
