- • Assume a dipole consisting of two different charges with different potentials, one +4V and the other -8V. They are a distance of 20 units of length from each other. First cal- culate the potential at each point and then construct one graph showing the potential as a function of distance between the charges. Show on the same graph the potential for each charge separately as well as for the combined (total) potential.
