A small piece of dust of mass m = 1.0 mg travels through an electric air cleaner

Question:

A small piece of dust of mass m = 1.0 mg travels through an electric air cleaner in which the electric field is 500 N/C. The electric force on the dust particle is equal to the weight of the particle.

(a) What is the charge on the dust particle?

(b) If this charge is provided by an excess of electrons, how many electrons does that correspond to?
