In front of an earthed conductor a point charge +q is placed a shown in figure

Options

A. On the surface of conductor the net charge is always negative
B. On the surface of conductor at some points charges are negative and at some points charges may be positive distributed non uniformly
C. Inside the conductor electric field due to point charge is non zero
D. None of these

Answer

B, C

Explanation

Charge is distributed over the surface of conductor in such a way that net field due to this charge and outside large q is zero inside. Field due to only q is non zero
