The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

A water droplet of radius 0.0022 mm remains stationary in the air. If the electric field of the Earth is 148 N/C downward, how many excess electron charges must the water droplet have? 5 N = electrons abo sin(x) Ox10" Submit Reset Reset All .Since the raindrop is stationary, the downward gravitational force is balanced by the upward electrostatic force. The gravitational force is given by my, where m is the mass of the drop and g = 9.80 m/s2. .The density of water is 1.00 g/cm. What is the volume of a spherical raindrop of radius r
