EQUILIBRIUM CHARGE DISTRIBUTION IN THE SPACE BETWEEN A CONDUCTING WIRE AND A CO-AXIAL METAL CYLINDER IN CLASSICAL APPROXIMATION: A PEDAGOGICAL COMMUNICATION

We consider a classical electron gas filling the space between a conducting wire and a metallic cylinder. In this pedagogical communication, we shall investigate the functional dependence of the electric charge density on the radial distance from the wire in thermal equilibrium and also analyse its experimental importance giving a statistical interpretation.
