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?
What is the strength of the
electric field at the position indicated by the dot in the figure?
What is the direction of the electric field at the position
indicated by the dot in the figure? (Assume that x-axis is
horizontal and points to the right.)

A raindrop of mass 4.0 mg and radius 2.0 mm has acquired an electric charge of 15x10^-15 C. The raindrop is located at the bottom of a cloud that is 500 m above the surface of the earth where the electric potential is -10^9 V with respect to the ground. What is the ratio of the electric potential energy of the raindrop compared to the gravitational potential energy? ANS: -7.7x10^-4 I just don't know how to solve the problem.
