Honeybees acquire a charge while flying due to friction with the air. A 130 mg bee with a charge of + 23 pC experiences an electric force in the earth's electric field, which is typically 100 N/C, directed downward. What is the ratio of the electric force on the bee to the bee's weight? What electric field strength would allow the bee to hang suspended in the air?
