Equilibrium of a charged test particle in the Kerr - Newman spacetime: force analysis

Abstract

In a previous work, we studied the equilibrium of a charged test particle placed in the combined gravitational and electromagnetic fields of a Kerr - Newman black hole. Recently, general relativistic analogues of inertial forces have been formulated. In this paper we analyse the inertial and the electromagnetic forces acting on the stationary test particle. This leads to an understanding of the behaviour of these forces as well as the mechanism of equilibrium.
