Point charge between parallel conducting planes. A charge is placed between two infinite planes, as in Figure 5.40.
(a) Place a system of coordinates so that the left plate is at x = 0 and the point charge is at (3d/4, 0). Find an expression for the potential at any point between the two plates as a sum on N image charges.
(b) Optional: Write a computer program that will evaluate the sum in
(a) for N = 7, N = 100, N = 1000 and N = 100,000, at x = 0.05 m, Y = 2.0 m using q = 1 X 10-12 C, d = 0.5 m. Compare the results and provide an indication of how many image charges are necessary for a maximum relative error of 1 %.

Determine the conductivity of silicon at T = 300 K if it is doped with donor impurity atoms at a concentration of 1.25*1016 cm-3. Assume that the electron and hole mobilities are 1350 cm2 / V-s and 480 cm2 / V-s, respectively.
If the thermal conductivity of the material is 20 W/m · K, estimate the heat transfer rate per unit length of the bar using a finite-difference method. Use the Gauss-Seidel method of solution with a space increment of 10 mm.
Design an op-amp astable multivibrator to have an output frequency of 400Hz and the frequency should be adjustable by plus or minus 20%. Use a 741 op-amp with supply of plus or minus 18 volts.
A piece of wave guide WG16 operating at 10GHz is used to make a wave guide termination by placing a thin resistive sheet at a distance 'd' from the short circuit. Calculate 'd' and the resistance per unit area of the sheet.
