Question

In a uniform electric field near the surface of the earth, a particle having a charge of -2.0 x 10^-9 C is acted on by a downward electric force of 3.0 x 10^-6 N. (a) Find the magnitude of the electric field. (b) what are the magnitude and direction of the electric force exerted on a proton placed in this field? (c) what is the gravitational force on the proton? (d)What is the ratio of the electric force to the gravitational force in this case?​
