SUMMARY
The gravitational field strength at the radius of a satellite's orbit is determined by the planet's mass and density. When the planet's density is doubled, the gravitational field strength increases proportionally, resulting in a new strength of 24 N/kg. Doubling the satellite's mass does not affect the gravitational field strength at its position, as gravitational field strength is independent of the mass of the object within the field. The relevant formula for gravitational force is F = Gm1m2/r^2, but it is crucial to note that gravitational field strength is a property of the mass creating the field, not the mass experiencing it.
