Satellite Orbiting around the Earth (gravitational fields)

  1. Jan 16, 2012 #1
    1. The problem statement, all variables and given/known data
    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


    Mass of Earth= 5.98x1024 Kg
    Radius of Earth= 6.38x106 m

    3. The attempt at a solution

    r= 8.15x106

    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?

    Well, they did ask for radius, not altitude.

    Ya I kind of answered my own question as I typed it up here, thanks for the advice
