Asolid sphere of radius a = 5 cm is centered at the origin. it is made of an insulating material and carries a uniform charge density with total charge q1 = +10 mu or micro cc. it is surrounded by a hollow, concentric conducting shell of inner radius b = 15 cm and outer radius c = 20 cm. the outer shell has total charge q = -5 mu or micro cc.
