Results for charged disks with different forms of surface charge density

Abstract

The equilibrium surface charge density of a charged disk is strikingly different from that of a uniformly charged disk. This dissimilarity is reflected on the corresponding Coulomb electrostatic potentials that they create. However, it is shown in this work that the Coulomb self-energy of these two differently charged disks is not much influenced by the pronounced difference that exists between their corresponding surface charge density distributions.
