Multipole Expansion of Potential

Click for details

The large distance expansion of potential due to a localized charge distribution is obtained. The first three terms receiving contributions from the monopole, the dipole moment and the quadrupole moment are explicitly displayed.  Important properties of dipole and quadrupole moment are discussed.
