1. The problem statement, all variables and given/known data Does the centripetal force equal the gravitational force? 2. Relevant equations Fg = G(m1)(m2) / r^2 Fc = 4(pi^2)(m)(r) / T^2 3. The attempt at a solution I have the mass of a satellite in geosynchronous Earth orbit. The period of Earth's orbit, and the Earth's radius and mass. I need to find the distance of the satellite above earth. Is it right to set Fc = Fg?
