Remove the charges and place a positive charge in the center of the grid. Draw five equipotential circles with the potentials of 10 Volts, 8 Volts, 6 Volts, 4 Volts and 2 Volts. (It might be hard to get the precise values but try to get as close as you can). Take an electric field sensor and move it in a straight line, crossing the equipotential lines. Describe the relationship between the distance between
