Inside a charged conductor in electrostatic equilibrium,
AThe electric field is non-zero and points outward
BThe electric field is zero everywhere
CThe electric field is equal to its surface field
DThe potential is zero
Answer & Solution
Correct answer: B. The electric field is zero everywhere
One of the cardinal results: inside a conductor in electrostatic equilibrium, E = 0 everywhere. Potential is constant (not necessarily zero) inside and equal to the surface value.
