Celestial mechanics question

    I've bumped into a little problem while solving some tests for my physics course, so I'd appreciate some help :) :
    Consider an artificial satellite circling around the Earth; how much times is the absolute value of it's gravitational potential energy greater than it's kinetic energy?

    Write down the expressions for gravitational potantial energy (say Eg) and the kinetic energy (say Ek).

    Question is what is 'n' where

    Eg * n = Ek

    You will have to use the equilibrium condition for the orbital motion of the satilite around the earth to get rid of the velocity from Ek.
