1. The problem statement, all variables and given/known data Hi, I've been having problems visualizing and interpreting a situation where there is zero potential in a point, equidistant, between two opposite charges. What is the significance of this? Here's a sample problem: Consider two point charges. One has a charge of +1 μC and the other has a charge of 1 μC. Consider a point P on the line connecting the charges. The point is the same distance from each charge. Which one of the following statements is true concerning the electric field and the electric potential at P? 2. Relevant equations Electric potential formula: V= ke Qsource/r 3. The attempt at a solution I know that at the equidistant point of the two opposite charges, the electric potential cancels out. Since electric potential is defined as the work done per charge of a positive charged particle to move it from infinity to a point under the influence of a source charge; does the zero potential between the two charges mean that it takes zero work to bring a charge from infinity to that point?
