A 0.10 g honeybee acquires a charge of +23 pC while flying.
a. The electric field near the surface of the earth is typically 100 N/C, directed downward. What is the ratio of the electric force on the bee to the bee's weight?
b. What electric field strength and direction would allow the bee to hang suspended in the air?
What is the charge on A so that the force on B is zero.
