Earth has a net charge that produces an electric field of approximately 168 N/C downward at its surface. The radius of the Earth is ~ 6.37×10^6 m. (a) What is the amount of excess charge on the Earth, noting the electric field of a conducting sphere is equivalent to a point charge at its center, in coulombs? (b) What magnitude of acceleration, in meters per second squared, will the field produce on a free electron near Earth's surface? (c) What mass (with the charge of a single extra electron) will have its weight supported by this field? (in kilograms)
