115. 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 o be the potential along some reference axis (which intersects the plane of our figure, shown next, at the xy coordinate origin, placed midway between the bottom two line charges — that is, the midpoint of the bottom side of the equilateral triangle) at a distance r f = a from each of the bottom wires (and a distance a 3 from the topmost wire). Thus, each side of the
