A thin rod lies on the z-axis with one end at - A and the other end at A, as shown in the diagram. A charge of Q is spread uniformly over
the surface of the rod. We want to set up an integral to find the electric field at location < 0, y, 0> due to the rod. Following the
procedure discussed in the textbook, we have cut up the rod into small segments, each of which can be considered as a point charge. We
have selected a typical piece, shown in red on the diagram.
