Abstract

The problem of the equilibrium stability of a body in an electric field has various technical and technological applications. One of the priorities is the implementation of the stable levitation of a body in the vacuum in an electric field, on the basis of which it is possible to construct high-sensitive sensors of acceleration. Currently, the technical solutions to ensure the stability of levitation state are based on approaches – the control of electrodes potentials and dynamic stability. The paper presents the solution of the problem of dynamic equilibrium stability of a charged conducting sphere near the center of a thin circular electrode to which an alternating voltage is applied. It is shown that the stable equilibrium is possible if Coulomb force is greater than interaction force of induction charges with the field.
