For both 90 degrees and 45degrees, the charge becomes more positive (-8V to 1.1V and -6.3V to 0.9V) when it goes farther away from sphere B which has 3000V. Because opposite charge attracts each other as positive charge attract negative charge, thus the closer the side of sphere A is to sphere B, the more negatively charged the side. Also, positive charges on sphere A is further away because like charges repel each other.For V-2According to experimented data, when the net charge on sphere A is negative, both 90 degreesand 45 degrees, the charge becomes more positive (-14V to -1V and -10V to -1V) when it goes fartheraway from sphere B which has 3000V. Because sphere B is positively charged so it attracts negativecharge from Sphere A. Thus, the side of sphere A where it is closer to sphere B is more negativelycharged. In addition, the reason why there are few negative charges on the furthest positions from sphere B is because negative charges present in sphere A repel each other. For V-3According to experimented data, when the net charge on sphere A is positive, both 90 degrees and45 degrees, the charge becomes more positive (6V to 7V and 0V to 6V that are relatively positive than V-1 and V-2) when it goes farther away from sphere B which has 3000V. As opposed to V-1,the same sign of charge repels each other. Since sphere A and B are both positively charged, thecharges repel each other and it becomes less positive for the positions that are closer to sphere B. Also, the reason why there are few positive charges at the furthest position is because like charges on sphere A repel each other.For V-4According to experimented data, when the net charge on sphere A is positive and there is noexternal electric field effecting sphere A, the charge on sphere a should be evenly distributed allaround the sphere due to the absence of external field. Also, because it has a spherical shape, a symmetry allows the charges to be evenly distributed. Thus, the charges are supposed to have thesame value regardless of degrees that we measured. Our measured data did not show the samenumber but they have relatively same value compared to
