Figure 3. Graph of Voltage (V) vs. Distance away from Negative Electrode (r) On a 2 dimensional surface, the electric potential at a point P away from a "point" charge is given by V(r) =2KQ In(r0/r) where V(r) ac In(r0/r) Table IV: Voltage Recorded from Distance'r' from Negative Electrode on a Horizontal Line for point charges with values of In(r0/r) where r0 = 0.20 m r (m) In(r0/r) V(r) (V) 0.01 = 0.005 2.996 0.405 = 0.0005 0.03 = 0.005 1.897 1.336 =0.0005 0.05 = 0.005 1.386 2.231 = 0.0005 0.07 = 0.005 1.050 3.265 = 0.0005 0.09 = 0.005 0.7850 3.130 = 0.0005 0.11 = 0.005 0.5978 4.735 = 0.0005 0.13 = 0.005 0.4308 4.973 = 0.0005 0.15 = 0.005 0.2877 4.520 = 0.0005 0.17 = 0.005 0.1625 5.282 = 0.0005 0.19 = 0.005 0.0513 5.502 = 0.0005 Figure 4.
