From the basic property of conductor we can say that the all entire charges will appear on the outer surface of any conductor and surface of the conductor is a equipotential surface. As the shape of conductor is irregular, the charge density will be different for every point on the surface. The electric field is not constant outside the conductor because it will vary with distance from the center.
