Picture of Apparatus:  

This data chart displays the position of the red probe from the black probe. The black probe remained stationary at the silver circle. Every cross on the black paper is distance one cm away. The Voltage increased as the red probe came closer to the silver line. 13-17 the voltage began to decrease.

This is a graph of Voltage versus Distance. The graph displays an exponential curve. This means that the closer it got to the silver line the higher the voltage.   

This is a chart of a charge a distance away from a ring. The values to the left is a constant radius away. The Voltage is a result of how the integral of the electrical field. The next column has a change in radius. This is different from the first column because the charge is constant distance away from the top of the ring, therefore the distance from the charge with the ring is changing .
