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

Text Solution

Verified by Experts

The correct Answer is:
D
Electric field,`E=-"dV"/"dr" "or" dr prop 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.
