Question

Equipotential surfaces

• A. are closer in regions of large electric fields compared to regions of lower electric fields
• B. will be more crowded near sharp edges of a conductor
• C. will always be equally spaced
• D. both (a) and (b) are correct

Answer 1

Answer: (D)

both (a) and (b) are correct

Answer 2

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