Unformatted text preview: is forced to be zero. An infinitesimal dipole is located above the plane at ) , , ( h with > h . At the observation point r r , obtain the electric potential produced by the dipole a) when its dipole moment is z p p o ˆ = r , and b) when its dipole moment is x p p o ˆ = r . c) Simplify the above results when r h r << . Problem 4 Assume two grounded infinite copper plates located at h z − = and h z = with > h . A point charge q is located at ) , , ( . Find the location and value of image charges for this configuration. What is the total charge induced on each plate? Problem 5 Suppose that the half space ≤ z is occupied by a dielectric material the susceptibility of which is χ . The upper half space > z is free space. A surface charge having a constant density of s ρ is positioned at the plane h z = in the upper half space. Determine the polarization vector in the lower half space. M. Shahabadi...
