Hence if we remove the charge -q at B and distribute electricity over the surface PO with a surface density a, according to the Coulomb-Poisson law, a = qAO/21rAP3, the field of force to the left of PD will fulfil the required boundary conditions, and hence will be the law of distribution of the ind
