PhysicsQ&A LibraryThe 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?Question

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*?
