Final answer:
Equipotential surfaces are surfaces in which the electric potential is the same at every point. They are used to map the electric field around a charged object or system. The spacing between equipotential surfaces depends on the charge density.
Step-by-step explanation:
Equipotential surfaces are surfaces in which the electric potential is the same at every point. They are used to map the electric field around a charged object or system. In this case, near a very large uniformly charged metal plate carrying a surface charge density σ = 0.62 μC/m², the equipotential surfaces would be drawn closer together. The charge density determines the spacing between the equipotential surfaces, so higher charge densities result in closer spacing.
