Question

Point between two charges where electric field is zero

Answer 1

Answer:

There is no zero-field point for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.

Explanation:

In a Phet Lab simulation, which is all I have at the moment to do my learning on electric field forces, the point represented as colored on the diagram below is shown to have an electric field magnitude of 0. I can see why from the arrowhead diagrams, but how can I explain this? Is it simply that the repulsion of the equidistant point charges creates a dead zone?
