Electrostatics : A solid conducting sphere of radius a carries a net positive charge 3Q. A conducting spherical shell of inner radius b and outer radius c is concentric with the solid sphere and carries a net charge -Q. 3 30 Using Gausss law, find the electric field strength in the regions labeled 1, 2, 3 and 4 when the entire system is in electrostatic equilibrium. (Denote the distance from origo as r)
