What is the charge on the dustparticle

Reference no: EM13555219

A small piece of dust of mass m = 2.5 µg travels through an electric aircleaner in which the electric field is 447 N/C. The electric force on the dust particleis equal to the weight of the particle.

a) What is the charge on the dustparticle?
b) If this charge is provided by an excess of electrons, how manyelectrons does that correspond to?
