Conductor PropertiesMediumQuestion 31430

Question

Excess charge on a conductor:
  1. A
    Distributes uniformly throughout volume
  2. B
    Resides on the surface only
    Correct
  3. C
    Concentrates at the centre
  4. D
    Stays where placed

Correct answer

Resides on the surface only

Explanation

Charge redistributes to outer surface. If any charge were inside, Gauss's law would require an E field there — but E = 0 inside conductor, so no charge can reside inside.
