B. Data Summary Graph the equipotential lines in the disc-rod configuration in the grid provided. Indicate the value of each equipotential line. Draw the electric field vectors at the points where the highest voltage equipotential line intersects with the lines r = 0, ±2, and ±4. Make sure that the arrows point in the appropriate directions and show the relative magnitudes of the electric field. In your diagram, indicate the sign of the charge for each electrode.
