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?
