The center of a moon of mass m is a distance D from the center of a planet of mass M. At some distance x from the center of the planet, along a line connecting the centers of planet and moon, the net force on an object will be zero. (a) Derive an expression for x. (b) If the net force is zero a distance 2/3 D from the planet, what is the ratio R of the mass of the planet to the mass of the moon, M/m?
