Please show work on paper and circle answer Raindrops acquire an electric charge as they fall. Suppose a 2.5-mm-diameter drop has a charge of +15 pC; these are both typical values. If the strength of the earth's electric field is 100 N/C, how does the magnitude of the electric force on the droplet compare to the weight force?
