Electric field,
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.

Equipotential surfacesa)are closer in regions of large electric fields...
Equipotential surfaces
Equipotential surfaces are imaginary surfaces in space where the electric potential is the same at every point on the surface. In other words, all points on an equipotential surface have the same electric potential.
a) Closer in regions of large electric fields
When the electric field is strong, the equipotential surfaces are usually closer together. This is because the electric field is the negative gradient of the electric potential, and the electric field lines are perpendicular to the equipotential surfaces. So, in regions of large electric fields, the equipotential surfaces have a steeper slope, causing them to be closer together.
b) More crowded near sharp edges of a conductor
Equipotential surfaces are more crowded near sharp edges of a conductor. This is because electric field lines tend to concentrate near sharp points or edges due to the higher charge density. Since the electric field lines are perpendicular to the equipotential surfaces, the equipotential surfaces will be closer together near sharp edges.
c) Equally spaced
Equipotential surfaces are not always equally spaced. The spacing between equipotential surfaces depends on the distribution of charge and the shape of the conductors or objects creating the electric field. In general, equipotential surfaces are closer together in regions of strong electric fields and farther apart in regions of weak electric fields.
d) Both (a) and (b) are correct
The correct answer is option (d) - both (a) and (b) are correct. Equipotential surfaces are indeed closer in regions of large electric fields compared to regions of lower electric fields, and they are more crowded near sharp edges of conductors. This is due to the relationship between the electric field, electric potential, and the geometry of the conductors or objects producing the electric field.
