A water droplet of mass 3.00 × 10−12 kg is located in the air near the ground during a
stormy day. An atmospheric electric field of magnitude 462 N/C points vertically
downward in the vicinity of the water droplet. The droplet remains suspended at rest in the
air. (a) What is the weight of the drop? (b) What is the electric charge on the droplet? (c)
How many electrons does it have?
