At a particular instant the magnitude of the gravitational force exerted by a planet on one of its moons is . If the

mass of the moon were three times as large, what would the magnitude of the force be? If instead the distance between the

moon and the planet were three times as large (no change in mass), what would the magnitude of the force be?
