What is true of a conductor in electrostatic equilibrium? Electrostatic equilibrium means that there is no current, i.e., no moving charges.  More than one choice may be true. Circle all true The electric field inside a conductor in equilibrium is zero. This is because any external electric field will cause the free charges in the conductor to redistribute to the surface until the electric field of these charges cancel out the external electric field leading to no net field inside the conductor. The electric field is always zero inside a conductor even if there

  • The electric field inside a conductor in equilibrium is zero. This is because any external electric field will cause the free charges in the conductor to redistribute to the surface until the electric field of these charges cancel out the external electric field leading to no net field inside the conductor.
  • The electric field is always zero inside a conductor even if there is a current going through the conductor.
  • The electric field just outside the surface of the conductor is always perpendicular to the surface.
  • The electric field just outside the surface of the conductor is always parallel to the surface.
  • The electric field just outside the surface of the conductor is always zero.
  • Any unbalanced charge must be on the surface of the conductor.
Expert Solution
Step 1

For conductors these points must be true 

1. The electric field inside a conductor in equilibrium is zero. This is because any external electric field will cause the free charges in the conductor to redistribute to the surface until the electric field of these charges cancel out the external electric field leading to no net field inside the conductor.

2. The electric field just outside the surface of the conductor is always perpendicular to the surface.

3. Any unbalanced charge must be on the surface of the conductor.
