A plane that is infinite in two dimensions, but with a finite thickness d carries a uniform volumetric charge density p. a) Find the electric field in the regions: i) ii) b) Point P is located a distance x from the center of the plane, on a line perpendicular to the plane's surface, as shown. How far away from point P (and in what relative location) would you need to place a point charge q so that the electric field at P is now zero? Your answer should be in terms of the variables given, and fundamental constants. VI AI

In the early 1900's Robert Millikan discovered the peculiar property that charge came in little packets, no smaller than e = 1.602 x 10-19 C -- he had measured the charge of the electron. Here's (roughly) how he did it. He removed an electron from an initially neutral droplet of oil with diameter 0.5 ??μm. In a vacuum, he positioned the droplet between two metallic plates separated by 6 mm and fiddled with the potential (voltage) across the plates until the droplet would hover against the force of gravity. Droplets of this size with +e charge would hover, but only for a particular voltage (otherwise they would sink or rise). Given the parameters stated here, and the fact that the density of the oil was 831 kg/m3, what was the voltage that made the droplets hover? (give your answer with 0.1 V precision)
