A 500 kg satellite experiences a gravitational force of 3000N while moving in a circular orbit around the Earth.

Find the radius of the orbit

2. Relevant equations

F_{G}=GM_{1}M_{2}/r^{2}

g=GM_{E}/r^{2}

Mass of Earth= 5.98x10^{24}Kg

Radius of Earth= 6.38x10^{6}m

3. The attempt at a solution

F_{net}=F_{G}

3000N=GM_{E}M_{S}/r^{2}

r=√[(6.67x10^{-11})(5.98x10^{24})(500)/3000]

r= 8.15x10^{6}

DO I subtract the radius of the Earth from my answer for radius of sattellite? OR would that give me the altitude, and they just want radius?
