Suppose that electrical attraction, rather than gravity, were responsible for holding the Moon in orbit around the Earth. If equal and opposite charges Q were placed on the Earth and the Moon, what should be the value of Q to maintain the present orbit? Use these data; mass of Earth = 5.98 X 1024 kg, mass of Moon = 7.35 X 1022 kg, radius of orbit = 3.84 X 108m. Treat the Earth and Moon as point particles.
