3. The bioelectric dipole described in problem 3 is moving along its axis along the z-direction from (0,0,-100) to (0,0, +100). A monitoring electrode located at (10, 10, 0) is used to record the potential O due to the bioelectric dipole. Use Matlab or otherwise to plot O as a function of z. Locate the maximum and minimum potential points.
