Top best answers to the question «Why is electric potential zero opposite charges»
Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero.

The potential energy at any point in space is the sum of potential energies contributed by each charge. Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero.
Where the electric field is 0 between two equal and opposite charges? The electric field strength E is nowhere zero in such a case. But there is also a potential that describes the configuration of charges. So when it comes to the electric potential around two equal and opposite charges then it is zero.. where you define it to be zero.
Since the plane between the equal and opposite charge is an equipotential plane, the potential difference between all point on that plane is zero. Thus there is no voltage gradient between all points on the plane (∇ V = 0).

In the example given in the question, the potential is zero in the mid-point, but it changes quite rapidly when one moves towards one charge or the other. So, although the electric potential is zero, the field is nonzero. Let me try to explain by analogy. The case of a car on a road is analogous to this.
True this is what the electric intensity and potential gradient relation says. But for the current question, the electric field is nowhere zero between the charges. The test charge midway will have the tendency to move towards negative charge. So if E≠0 at the midpoint, then ΔV≠0, Still a lot of confusion for me.
