Raindrops acquire an electric charge as they fall. Suppose a 2.4-mm-diameter drop has a charge of +12 pC. In a thunderstorm, the electric field under a cloud can reach 15,000 N/C, directed upward. For a droplet exposed to this field, how do the magnitude of the electric force compare to those of the weight force?

Honeybees acquire a charge while flying due to friction with the air. A 120 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? F/W = ______ What electric field strength would allow the bee to hang suspended in the air? E= _______ What electric field direction would allow the...
