Question
Describe schematically the equipotential surfaces corresponding to a a single positive charge at the origin.
Solution
The surfaces where the potential has a constant value are called equipotential surfaces.
The equipotential surfaces corresponding to a single charge at the origin are concentric spheres centered at the origin. With increase in distance from the origin, seperation between the equipotential also differ.
