Imagine for a moment that the moon is held in its orbit about the earth by electrical forces rather than by gravitation. What is the necessary electrical charge -Q that would be on the earth and +Q that would be on the moon to hold the moon in a circular orbit of 27.3 days? The Earth moon distance is 384,000 km and the mass of the moon is 7.35 x 1022 kg.
