At the earth’s surface there is a measurable electric field of 150 N/C that is directed down (towards the center of the earth). This implies that the solid part of the planet (from the surface to the core) has a net electric charge. Assuming that earth is a conductor, calculate (a) the sign of this charge (+ or –), (b) the surface charge density, (c) the total surface charge of the earth and (c) the number of elementary charges that...
