116. From the previous chapter, we know that the radial field due to an infinite line- source is E r = λ 0 ε which integrates, using Eq. 24-18, to obtain VV dr r V r r if r r f f i i f =+ F H G I K J z λ λ 00 εε ln . The subscripts i and f are somewhat arbitrary designations, and we let V i = V be the potential of some point P at a distance r i = r from the wire and V f = V o be the potential along some reference axis (which will be the z axis described in this problem) at a distance r f = a from the wire. In the “end-view” presented here, the wires and the z axis appear as points as they intersect the xy plane. The potential due to the wire on the left (intersecting the plane at x = –a ) is () negative wire 2 2 0 ln , 2 o a xa y  −λ  π ++  and the potential due to the wire on the right (intersecting the plane at x = +a ) is positive wire 2 2 0 ln . 2 o a y
