Assume that electrical attractions, rather than gravity, were responsible for holding the Moon in orbit around the Earth.
Part A
If equal and opposite charges Q were placed on the Earth and the Moon, what must be the value of Q to maintain the present orbit? Utilize these data: mass of Earth=5.98×1024kg, radius of orbit=3.84×108m, mass of Moon=7.35×1022kg,. Treat the Earth and Moon as point particles.
