Dust grains (r'= 1μm) in Saturn's rings are in a region of dilute ionized gas. Thus, these dust grains can pick up electrons. If the electric potential at the surface of a dust grainis400 V, determine the number of electrons on the surface of that dust grain. Assume thatthe electrons are distributed spherically and that the individual dust grains are far enoughapart that their electrons don't a ect each other.
