Worked practice questions

Under electrostatic equilibrium, the net electric field in the **interior** of a conductor is:

  1. Equal to $\sigma/\varepsilon_0$
  2. Directed along the surface
  3. Zero
  4. Equal to the surface field
Show answer and solution

Correct answer: C. Zero

If E inside were non-zero, free electrons would accelerate — that contradicts equilibrium. **Hence E_inside = 0; consequently the conductor's interior is at a single potential.**
