Unformatted text preview: each with a round crosssection, but its own diameter. Both diameters, D 1 and D 2 , are much smaller than the distance d between the wires. Compare the result with that for two spheres, and interpret the difference. Problem 2.3 (20 points). Using the results for a single thin, round, conducting disk, obtained in class, consider a system of two such disks at a small distance d << R from each other  see Fig. on the right. In particular, calculate: (i) the reciprocal capacitance matrix of the system, (ii) the mutual capacitance between the disks, (iii) the partial capacitance, and (iv) the effective capacitance of one disk, (all in the first nonvanishing approximations in d / R << 1). Compare the results (ii)(iv) and interpret their similarities and differences. a b a d R...
