Two straight bars of length L have equal but opposite uniform linear charge densities with magnitude 1 and are oriented perpendicular to each other as shown. Point P is located a L perpendicular to the midpoint of each bar. In terms of the variables given and 2 distance fundamental constants, a) Relative to infinity, what is the electric potential at point P? b) What would be the change in potential energy of this collection of charges if a charge +Q was brought from infinity to point P?
