The Quadrupole Moment of a Homogeneously Charged Ellipsoid cover

The Quadrupole Moment of a Homogeneously Charged Ellipsoid

Published in Electrodynamics / Electrostatics / Multipole Moments
Tags: Rotational Symmetry / Quadrupole Moment / Ellipsoidal coordinates

The quadrupole moments of a homogeneously charged ellipsoid are calculated. The result will help us to understand how and why the quadrupole moments of an ellipsoidal charge distribution changes if it gets into an excited state.
