b. A photocopy machine works by arranging positive charges (in the pattern to be copied) on the surface of a drum, then gently sprinkling negatively charged dry toner (ink) particles onto the drum. The toner particles temporarily tick to the pattern on the drum and are later transferred to paper and melted to produce the copy. Suppose each toner particle has the mass 9.5 x 10-17 kg and carries an average of 20 extra electrons to provide an electric charge. Assuming that the electric force on a toner particle must exceed thrice its weight in order to ensure sufficient attraction, compute the required electric field strength near the surface of the drum
