Question

Equipotential surfaces

• A. will always be equally spaced.
• B. are closer in regions of large electric fields compared to regions of lower electric fields.
• C. will be more crowded near regions of large charge densities.
• D. will be more crowded near the sharp edges of a conductor.

Answer 1

Answer: (B), (C), (D)

will be more crowded near the sharp edges of a conductor.

Equipotential surfaces:

1. The equipotentials are evenly spaced and parallel between the only plates. So, Equipotentials will not always be equally spaced.
2. Equipotential surfaces are closer in regions with high electric fields than in regions with low electric fields.
3. Charge density is higher at a conductor's sharp edges.
4. As a result, the electric field is stronger.
5. As a result, equipotential surfaces are more crowded.
6. It is clear from the diagram that equipotential surfaces are not at equidistance, hence option (A) is incorrect.

Hence, options (B), (C), (D) are correct.
