A positive charge +Q is placed outside a neutral conductor. Inside the conductor is a cavity containing no charge. What is the electric field at the “center” of the cavity, a distance D from the charge +Q?

  1. kQ/D2, direction away from the charge Q
  2. kQ/D2, direction toward the charge Q
  3. kQ/D2, direction away from the center of the conductor
  4. kQ/D2, direction toward the center of the conductor
  5. E = 0
  6. Cannot determine the electric field
