Question

If electric field is zero in a region do you think potential difference at the region will also be zero?

Answer 1

The electric field due to a positive point charge points radially away from the charge, and the electric field due to a negative point charge points radially toward the charge. ... The zero field point for like sign charges will be between the charges, closer to the smaller charge (and in the middle for equal charges).

Answer 2

Yes the potential difference at the region will also be zero.
