Problem 6. Rings around the moon The mass of the Earth is 5.97 × 1024 kg. Our moon has a mass of 7.35 x 1022 kg and a radius of 1.74 × 106 m. (a) At what point directly between the centers of the Earth and the moon will a small body experience zero net gravitational force due to these two bodies? (b) A spacecraft is maintaining a circular orbit around the moon, near its surface. How much more mechanical energy per unit mass of the spacecraft must it gain in order to reach the point in (a)?
