Question:

A charged cloud system produces an electric field in the air near Earth's surface. A particle of charge – 2.0 x 10-9 C is acted on by a downward electrostatic force of 3.0 x 10-6 N when placed in this field.

(a) What is the magnitude of the electric field? What are the

(b) Magnitude and

(d) What is the magnitude of the gravitational force Fg on the proton?

(e) What is the ratio Fel/Fg in this case?
