Very close to either one of the charges, the equipotential curves are
approximately circular.
Very close to either one of the charges, the equipotential curves get
closer together as you get closer to the charge.
Very far from both charges, the equipotential curves are approximately
circular.
In the intermediate region where there are still distinct equipotential
curves around each charge, the equipotential curves are closer together
on the side away from the other charge.
