4-1. A long conducting cylinder bearing charge l per unit length is oriented parallel to a grounded conducting plane of infinite extent. The axis of the cylinder is a distance d from the plane and the radius of the cylinder is R. Find the location of the line image. Can you determine the potential for all space?
4-2. A point dipole p is placed at the center of a solid dielectric sphere of radius R and dielectric constant e. Find the electric field at points inside and outside the sphere. (Hint: The field outside is a dipole field; inside another term is needed in addition to the dipole.)
4-3. Problem 4.8 in Jackson
