Gauss's Law in DielectricHardQuestion 31598

Question

In Gauss's law for dielectrics, the displacement vector D is defined so that the flux depends only on:
  1. A
    Bound charges
  2. B
    Free charges
    Correct
  3. C
    Total charges
  4. D
    Polarisation

Correct answer

Free charges

Explanation

∮ D·dA = Q_free_enclosed. D = ε₀E + P absorbs the effect of bound charges, leaving only free charge on the right side.
