A dipole with if = (33:1021 Coulomb - metres) 2 is located on the zaxis a distance 2 metres above an infinite grounded conducting plane (x-y plane). What is the total electric potential at a point P with spherical coordinates (6m, 3%)? [use the method of images! Assume 60 everywhere. Also, recall that for dipoles, V(F) = at\" = 4;;2]
