Question

Equipotential surfaces.

• A. Are closer in regions of large electric fields compared of lower electric fields
• B. Will be more crowded near sharp edges of a conductor
• C. Will always be equally spaced
• D. Both (1) and (2) are correct

Answer 1

Answer: (D)

Both (1) and (2) are correct

Answer 2

: Electric field, $E = - \frac{dV}{dr}ordr \propto \frac{1}{E}$

i.e., equipotential surfaces are closer in regions of large electric fields compared to regions of lower electric field. At sharp edges of a conductor, charge density is more. Therefore electric field is stronger. Hence equipotential surfaces are more crowded.
