D due duccu surlaccuage deusiy.  Two semi-infinite grounded conducting planes Page 3 of 11 meet at right angles. In the region between the m, there is a point charge 'q as shown in the figure. Calculate the a) potential in the region of charge q b) induced charged densities and total induced charged on the two planes c) total electrostatic energy of the system d) suppose the planes met at some angle other than 90", would you still be able to solve the problem by the method of images? If not, for what particular angles does the method work?
