Question 6

An electrostatic precipitator is used to remove dust particles from industrial flue gases. A spherical dust particle initially carries a net positive charge of +3.2 × 10-16 C. As it passes through a corona discharge region, it absorbs a stream of electrons, reaching a final net charge of -8.0 × 10-16 C. How many electrons did the dust particle absorb from the corona discharge?
