non-zero and uniform. non-zero and radially symmetric. non-zero and non-symmetric

1. If a conductor carries a non-zero net charge but is in electrostatic equilibrium, the electric field inside it is… • non-zero and uniform. • non-zero and radially symmetric. • non-zero and non-symmetric • None of the above. • zero. Oregon State University PH 213, Class #9

2. If a conductor carries a non-zero net charge but is in electrostatic equilibrium, that net charge is… • on the outside surface of the conductor. • at the center of the conductor. • distributed uniformly throughout the volume of the conductor. • None of the above. • There is not enough information. Oregon State University PH 213, Class #9

3. We can use those two basic facts about any conductor that is already in electrostatic equilibrium (a: internal E-field is zero; and b: net charge resides on the outside surface), along with one more application of Gauss’s Law, to calculate the E-field strength “just outside” the surface of the conductor: Oregon State University PH 213, Class #9

4. We can also use the above results to deduce what must be true within hollow conductors (assuming, as before, that they are in electrostatic equilibrium).… Oregon State University PH 213, Class #9
