Whiteboard 3: Two Spheres Two spheres, A and B, each have an outer radius of 2.0 cm and each carry a charge of +12 nC. (a) Sphere A is a thin conducting shell with its +12 nC charge uniformly distributed over its surface. What is the value of the electric field just outside the sphere's surface? (b) Sphere B is a thick shell of insulating material with an inner radius of 1.0 cm and with the +12 nC charge uniformly distributed throughout the volume of the insulating shell. What is the value of the electric field: i. At the inside surface of the insulating shell (at radius 1.0 cm) ii. At the outside surface of the insulating shell (at radius 2.0 cm) At a radius of 1.5 cm iii.
