Final answer:
Equipotential lines of two equal negative charges are neutral zones representing points of constant electric potential, not areas of max or min potential energy, nor are they electric field lines.
Step-by-step explanation:
The equipotential lines of two equal negative charges do not represent areas of maximum potential energy, minimum potential energy, or electric field lines. Rather, they are lines that represent all points where the electric potential is constant, which means they mark areas where the potential energy would be the same for a charged particle. The electric field lines would be drawn perpendicular to these equipotential lines. Therefore, for two equal negative charges, the equipotential lines represent neutral zones where a test charge would have the same potential energy anywhere along a given line.
