Homework Help: Satellite, magnitude/acceleration problem

  1. Sep 26, 2005 #1
    Satellites are placed in a circular orbit that is 3.59*10^7 m above surface of earth. What is the magnitude of the acceleration due to gravity at this distance? A formula to use or the work would be appreciated. Thanks.

    I tried using F=G(m1*m2)/r^2. i didnt know the mass of the satellitle though so i was left with multple variables. I also tried using g, but that didnt work. I guess I really dont know how to start when the satellite has an unknown weight.
