Earth has a net charge that produces an electric field of approximately 150 N/C downward at its surface.
(a) What is the magnitude and sign of the excess charge, noting the electric field of a conducting sphere is equivalent to a point charge at its center?
(b) What acceleration will the field produce on a free electron near Earth's surface?
(c) What mass object with a single extra electron will have its weight supported by this field?
Determine out the greatest possible angular speed it can have for the matter at the surface of the star on its equator to be just held in orbit by the gravitational force.
