Physics 3323, Electromagnetism I, Spring 2002 EXAM #2 Wednesday, March 20, 2002 Remember to work each problem as fully as possible. Partial credit will be given so SHOW ALL OF YOUR WORK!! Useful information: [] θ πε ˆ sin ˆ cos cos sin sin + = = r r p E u u u du u u dipole 2 4 1 3 0 1. A point charge q is placed a distance d above the surface a semi-infinite slab of homogenous dielectric material (with relative permittivity ε r ). The surface of the slab is located at z=0. In this problem, we will find the potential above and below the surface using the method of images. Before you begin, here are a few hints: i) You have to use different image charge configurations for the regions z > 0 and z < 0. ii) For the region z > 0, the location of the image charge below the surface is where we would expect, but the presence of the dielectric will modify its magnitude (q’). iii) For the region z < 0, there is only one image charge (located above surface where we would expect), but it’s magnitude will also be different, too (q’’). iv) The usual boundary conditions for potentials at dielectric surfaces apply.
