A spaceship of mass m travels from the Earth to the Moon along a line that passes through the center of the Earth and the center of the Moon.

(a) At what distance from the center of the Earth is the force due to the Earth twice the magnitude of the force due to the Moon? (Astronomical data needed for this problem can be found on the inside back cover.)
(No Response) m (b) How does your answer to part (a) depend on the mass of the spaceship?
The distance is related to the square root of the spaceship's mass.The distance is independent of the spaceship's mass.    The distance is related to the square of the spaceship's mass.The distance is related linearly to the spaceship's mass.
Explain.
