Which property does NOT necessarily hold for a charged conductor in electrostatic equilibrium?
AThe conductor's surface is itself an equipotential surface plus charge sits uniformly inside the volume
BField inside the conductor is zero
CExcess charge resides only on the surface
DPotential is constant throughout the volume
Answer & Solution
Correct answer: A. The conductor's surface is itself an equipotential surface plus charge sits uniformly inside the volume
Excess charge cannot remain in the interior; it always migrates to the surface. The other three (E=0 inside, surface charge, equipotential surface) are all true.
