Each of the following statements about the electric field in a conductor at equilibrium was written by a different student. Select all those that are physically correct. At equilibrium the electric field inside a polarized conductor due to the charges accumulated at the surface of the conductor is zero, so the net electric field inside the conductor is equal to the electric field due to charges in the surroundings. At equilibrium the electric field inside a conductor at equilibrium is zero because electric fields due to charges in the surroundings cannot penetrate the material of the conductor. At equilibrium the electric field inside a polarized conductor due to the charges accumulated at the surface of the conductor is zero, and the electric field due to charges in the surroundings cannot penetrate the conductor, so the net electric field inside the conductor must be zero. At equilibrium the net electric field inside a conductor is zero because the conductor polarizes until the electric field inside the conductor due to charges at the surface is equal and opposite to the electric field due to charges in the surroundings. At equilibrium the net electric field inside a conductor must be zero, because if it were not zero, there would be charge flow because the drift speed of the mobile charges is proportional the the net electric field. At equilibrium the net electric field inside a conductor must be zero, because the average drift speed of the mobile charges is v¯=uEnet, and the only way for v¯ to be zero is if Enet=0.

Each of the following statements about the electric field in a conductor at equilibrium was written by a different student. Select all those that are physically correct.

At equilibrium the electric field inside a polarized conductor due to the charges accumulated at the surface of the conductor is zero, so the net electric field inside the conductor is equal to the electric field due to charges in the surroundings.
At equilibrium the electric field inside a conductor at equilibrium is zero because electric fields due to charges in the surroundings cannot penetrate the material of the conductor.
At equilibrium the electric field inside a polarized conductor due to the charges accumulated at the surface of the conductor is zero, and the electric field due to charges in the surroundings cannot penetrate the conductor, so the net electric field inside the conductor must be zero.
At equilibrium the net electric field inside a conductor is zero because the conductor polarizes until the electric field inside the conductor due to charges at the surface is equal and opposite to the electric field due to charges in the surroundings.
At equilibrium the net electric field inside a conductor must be zero, because if it were not zero, there would be charge flow because the drift speed of the mobile charges is proportional the the net electric field.
At equilibrium the net electric field inside a conductor must be zero, because the average drift speed of the mobile charges is v¯=uEnet, and the only way for v¯ to be zero is if Enet=0.
