Chapter , Problem 18(choose chapter or problem)
The electric field strength near the surface of Earth is about (a) Estimate the magnitude of the charge density on the surface of Earth. (b) Estimate the total charge on Earth. (c) What is value of the electric potential at Earths surface? (Assume the potential is zero at infinity.) (d) If all Earths electrostatic potential energy could be harnessed and converted to electric energy at reasonable efficiency, how long could it be used to run the consumer households in the United States? Assume the average American household consumes about of electric energy per month.
