Equipotential surfaces

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

Tardigrade Admin · Accepted Answer

Electric field, E=-(dV/dr) or dr propto(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

Q. Equipotential surfaces

are closer in regions of large electric fields compared to regions of lower electric fields

will be more crowded near sharp edges of a conductor

will always be equally spaced

both (a) and (b) are correct
