Suppose two clouds containing equal numbers of electrons, Ask an Expert

Academics

The remotest object visible to the unaided eye is the great galaxy Messier 31 in the constellation Andromeda. It is located 2.4x1022m from Earth. (By comparison, the sun is only about 1.5x1011m away.) Suppose two clouds containing equal numbers of electrons are separated by a distance of 2.4x1022m. If the magnitude of the electric force between the clouds is 1.0N, what is the charge of each cloud?
