$(a)$ Identify an equipotential surface of the system.
$(b)$ What is the direction of the electric field at every point on this surface?
$(a)$ The situation is represented in the given figure.
An equipotential surface is the plane on which total potential is zero everywhere. This plane is normal to line $AB.$ The plane is located at the mid-point of line $AB$ because the magnitude of charges is the same.
$(b)$ The direction of the electric field at every point on this surface is normal to the plane in the direction of $AB.$
