Repeat Problem 88. This time, assume the charges on the Moon and the Earth are not the same magnitude, but the ratio of the charges are the same as the ratio of their masses. Find (a) the charges on the Moon and the Earth and (b) the corresponding number of moles of electrons on each. (c) How does the force of the Moon on the Earth now compare with the force of the Earth on the Moon? Explain your answer.
(reference problem 88)
Imagine that the Moon is locked into its orbit around the Earth by electrical forces and the gravitational force between the Earth and Moon is somehow “turned off.” (a) A charge of what magnitude would need to be on each body? Approximate the Moon and the Earth as point particles and assume both have the same magnitude of charge. (b) How many moles of electrons would that be?
