INFINITE WIRE Consider an infinite line of charge with charge per unit length A. Calculate the electric field a distance z away from the wire. Namely z is the distance to the closest point on the wire.

In the figure below, a "semi-infinite" nonconducting rod (that is, the rod is infinite only in the positive y direction) has uniform positive linear charge density lambda. Two particles with charges +Q are located at distances a from the origin as shown. Remember: You must show every step of your calculations! What are the x- and y - components of the electric field produced by the rod at the origin? Show your work for calculating the electric field by labeling...

When we applied Gauss's Law to find the electric field of an infinite sheet of charge, we also treated the sheet as if it was very thin, like a sheet of paper. But if the sheet has an appreciable thickness, we can investigate the field within the sheet as well. Here are two views of a thick sheet of charge with my suggestion for a Gaussian surface, viewed both head-on and at an angle so you can see the distances:...
9. Electric Field Inside an Insulator (25 pts.) A spherical insulator has constant charge density, total charge > 0, and radius B. What is the magnitude of the electric field at a distance B/2 from the center of the sphere? Give the answer in terms of Q, B, and K, where K is the constant from Coulomb's law.
