The imaging drum of a photocopier is positively charged to attractnegatively charged toner particles. Near the surface of the drum,its electric field has magnitude 1.70 x 10^5 N/C. A toner particleis to be attracted to the drum with a force that is 7 times theweight of the particle.

(a) What must be the ratio of the mass of a toner particle to themagnitude of its net charge?

(b) If the toner particles are made of carbon (atomic number 6,atomic mass 12.0 g/mol), how many carbon atoms are there for eachexcess electron on a toner particle?
