प्रश्न
Write two important characteristics of equipotential surfaces.
Advertisements
उत्तर १
- Perpendicular to the Electric Field: At all times, equipotential surfaces are perpendicular to the direction of the electric field.
- No Work Done in Moving a Charge: Moving a charge along an equipotential surface requires no effort because the potential is constant throughout.
उत्तर २
- Potential remains the same at all the points on the equipotential surface.
- No work is required to move a charge within an equipotential surface.
