Question
A conductor is placed in a steady external electric field. Which of the following statements are correct for this situation? (There could be more than one correct choice.)
The electric field is zero inside the conductor.
All the free electrons go to the surface of the conductor.
The surface of the conductor is neutral.
The electric field just outside the surface of the conductor is perpendicular to the surface.
None of these statements are correct.
The electric field is zero inside the conductor.
All the free electrons go to the surface of the conductor.
The surface of the conductor is neutral.
The electric field just outside the surface of the conductor is perpendicular to the surface.
None of these statements are correct.
Explanation / Answer
When a conductor is placed in an external electric field. The electric field is zero inside the conductor. All the free electrons go to the surface of the conductor. The surface of the conductor is neutral. The electric field just outside the surface of the conductor is perpendicular to the surface. Hence the statements are true. ABCD are true.
