Abstract
Abstract: The gravitational oscillation of a dielectric fluid cylinder surrounded by gravitational
dielectric medium of negligible motion has been investigated via the normal mode analysis for
axisymmetric perturbation. The acting forces on the model are : self-gravitating, pressure gradient and
electrodynamic forces with oscillating time dependent electric field. The model is governed by
Mathieu second order integro-differential equation. The oscillating electric field is only destabilizing
in few axisymmentric states but it is strongly stabilizing in the remaining axisymmentric states.
The self gravitating has strong destabilizing influence in the domain 0
