The solutions to many problems involving electric fields are simplified by making use of equipotential surfaces. An equipotential surface is a surface:1. On which the potential is the same everywhere2. The movement of charge over such a surface would require no work3. The tangential electric field is zero4. The normal electric field is zeroWhich of the above statements are correct?
