Question

When is electric potential zero between two charges?

Answer 1

when the distance between 2 charges is infinity

Answer 2

⭐HEYA FRIEND!
⭐HERE'S YOUR ANSWER

The electric potential becomes zero at the midway point between two equal but opposite charges, and it is because at the midpoint electric field due to both the charges will be equal and opposite,
so work done by or on the charges at that point is zero therefor potential will be zero.
