Question

An insulating solid sphere of radius R has a uniform positive charge density $ρ$ . As a result of this uniform charge distribution there is a finite value of electric potential at the centre of the sphere, at the surface of the sphere and also at a point outside the sphere. The electric potential at infinity is zero.

Statement 1: Potential decreases uniformly from the centre to the surface of the sphere.

Statement 2: The magnitude of electric field at a distance $r (r < R)$ from the centre of the sphere is $\frac{ρ r}{3 \in_{0}}$ .
