Question

The potential ( relative to a point at infinity) mid way between two charges of equal magnitude and opposite sign is zero. can you think of a way to bring a test charge from infinity to this mid point in such away that no work is done in any part of the displacement?​

Answer 1

Answer:

The potential between two opposite and equal charges is zero because you make it zero by choosing the center point on a continuum. Think of any scale that runs ...
