A spacecraft is on a journey to the moon. the masses of the earth and moon are, respectively, 5.98 x 10^24kg and 7.35 x 10^22kg. the distance between the centers of the earth and the moon is 3.85 x 10^8m. at what point, as measured from the center of the earth, does the gravitational force exerted on the craft by the earth balance the gravitational force exerted by the moon? this point lies on a lie between the centers of the earth and the moon.
