Gravitational Binding Energy in Charged Cylindrical Symmetry

TL;DR

This paper investigates the gravitational binding energy of a static charged cylindrically symmetric object, revealing that only the localized mass contributes to binding energy, while the electric field does not.

Contribution

It introduces a distinction between localized and non-localized mass contributions to gravitational binding energy in charged cylindrical systems.

Findings

Localized mass contributes to gravitational binding energy.

Electric coupling does not contribute to binding energy.

Binding energy depends solely on the localized mass component.

Abstract

We consider static cylindrically symmetric charged gravitating object with perfect fluid and investigate the gravitational binding energy. It is found that only the localized part of the mass function provides the gravitational binding energy, whereas the non-localized part generated by the electric coupling does not contribute for such energy.
