You have a spaceship that is located between the Earth and the Moon. At the spaceship's current location (point A), the net gravitational force on the ship due to the Earth and the Moon is equal to 0. Throughout this problem, assume that the spaceship remains along a straight line between the Earth and the Moon.
Determine:
a. The distance of the spaceship from the Moon at point A.
b. The net gravitational force on the spaceship at point B (the point where the spaceship is twice as far from the Moon as at point A).
c. The distance of the spaceship from the Moon at point C (the other point in space where the net gravitational force on the spaceship is the same as at point B).
