Delicate measurements indicate that the Earth has an electric field surrounding it, similar to that around a positively charged sphere. Its magnitude at the surface of the Earth is about 100 N/C. What charge would an oil drop of mass 2.0 x 10-15 kg have to have, in order to remain suspended by the Earth's electric field? Give your answer in coulombs ?
