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 10-17kg 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

You have infinitely wide grounded conducting plates that have a finite thickness as shown in the figure. 바 ut H₁ Z q origin X tH tH = We want to find the voltage V(r) in the space between the conductors. A friend proposes to use the method of images. Their idea is to put i) a negative charge -q a distance d above the bottom surface of the top plate (at z 3d) and ii) put a negative charge -q at a distance d below the top surface of the bottom plate (at z = -d). Is the potential of the image charge distribution proposed a valid solution for the original problem? Briefly justify your answer.
