Which of the following statements are correct ? A. Inside a conductor, the electrostatic field is zero. B. Electric field at the surface of a charged conductor does not depend on its surface charge density. C. The interior of a charged conductor can have no excess charge in the static situation. D. At the surface of a charged conductor, the electrostatic field must be normal to the surface at every point. E. The elec

Step-by-step solution

Statement A is correct because in electrostatics, the free charges inside a conductor redistribute themselves such that the net electric field inside is zero. Statement B is incorrect because the electric field at the surface of a charged conductor is given by E = ₀ , which directly depends on the surface charge density . Statement C is correct because, by Gauss's law, since the electric field inside the conductor is zero, the net charge enclosed by any Gaussian surface inside the conductor must be zero. Thus, any
