A positive and negative charge are shown in (Figure 1) .
At which numbered position (or positions) is the electric potential zero?
Consi der the point x in between the two charges from the positive charge. From the observation of the figure,the distance between positive charge and the point is:x and distance between positive charge and point is 3-X The net potential 1s zero at that point. k24 kq_0 therefore, counting 2 units from the positive charge at 5 the potenti al is zero Consi der the another point x2 right to the negative charge The net potential 1s zero at that point. k2q k x-3 units Therefore, at 8 potential is zero.
