Homework Help: Gravitational field, density and mass.

  1. Jul 23, 2008 #1
    A satellite orbits a planet. The gravitational field strength at the radius of the orbit is 12 N/kg. What will the gravitational field strength at the position of the satellite be if
    - The planet's density is doubled?
    - The satellite's mass is doubled?

    I just don't understand their relationship. Any help is appreciated =)

    Do you know the formula for gravitational force?

    F = Gm1m2/r^2
    but doubling the mass doesn't double the force.
