Equipotential surfacesA. are closer in regions of large electric fields compared to regions of lower electric fieldsB. will be more crowded near sharp edges of a conductorC. will be more crowded near regions of large charge densitiesD. will always be equally spaced

Answer» Correct Answer - A::B::C
From `E = - (dV)/(dr)`, we find that `dr prop (1)/(E)`, i.e., equipotential surfaces are closer in regions of large electric fields compared to regions of lower electric fields. At sharp edges of a condutor, charge density is more. Therefore, electric field is stronger. Hence equipotentials surfaces are more crowded. Same argument is true for option (c). The choices (a), (b), (d) are correct.
