A uniform charged sphere with hole is a physical system that consists of a spherical shell with a hole in the center, surrounded by a uniform distribution of electric charge.
The charge in a uniform charged sphere with hole is evenly distributed on the surface of the sphere, with no charge present inside the hole.
Inside the hole, the electric field is zero since there is no charge present. Outside the sphere, the electric field is the same as that of a point charge located at the center of the sphere.
The electric potential inside the hole is constant and equal to zero, while outside the sphere, it decreases as the distance from the center increases, following the same pattern as a point charge.
The total charge of a uniform charged sphere with hole is the same as the charge on the surface of the sphere, since there is no charge inside the hole.
