Solution Summary

Solutions of three problems good to learn basics.---------
(1) A point charge is placed at the center of a conducting charged spherical shell. The field at any point and is calculated with other questions in four parts of the question. -------------
(2) A solid conducting charged sphere surrounded by an insulating shell of radii a and b. The field at any point, charge density and other quantities are determined in three parts of the question. ------------
(3) A uniformly charged wire is bent in semicircular ring. the potential at the center of curvature is calculated.
