Gravitation with conversions help!

  1. Feb 8, 2012 #1
    1. The problem statement, all variables and given/known data
    "At what height above planet B's surface (in meters) does the gravitational field intensity become 0.6 times its value on the surface of planet B, given that the radius of planet B is 6.40 x 10^3 km and that its mass is 5.97 x 10^24 kg?


    2. Relevant equations
    g=Gm/r^2


    3. The attempt at a solution
    My work is very scrambled with trying to convert and compare the values and I think my mistake could be in plugging in the new values.
