Which of the following diagram correctly shows the electrostatic properties of a charged conductor. (Given $V_o$ potential on the surface of conductor, ρ = Volume charge density.)

The correct answer is Option (3)

$\vec E$ is zero because there is no charge inside the sphere.

$P=0$ because there is no charge inside.

V = Constant = $0$ ⇒ Because it represents an equipotential surface.
