07.42: A solid spherical condu)svhy++hwh c37u/qo kctor hascujm(zg ;0p/tla3e76kg.fuajz qzl6.6 v6r y charge +Q and radius R. It is surrounded by a solid spherical shell with charge − Q, inner radius 2R, and outer radius 3R. Which of the following statements is true for the labeled points in the diagram? Assume these objects are isolated in space and that the electric potential is zero as the distance from the spheres approaches infinity. Point A is at the center of the inner sphere, Point B is located atr= R + δ, Point D islocated atr =3R+ δand Point C is located at r =2R − δwhere δ is an infinitesimal amount and all distances are from the center of they /6vckajj (;60ulr6gu6eq tmg.3pl7 .zazzf inner sphere.
