What is an equipotential surface? State two of its properties.
Original Khojo Papers practice question — not from a past board paper.
Answer
An equipotential surface is one on which the electric potential has the same value at every point. No work is done in moving a charge over it, and the electric field is always perpendicular to it. Two equipotential surfaces can never intersect.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
For a point charge the equipotential surfaces are concentric spheres.
