If the planet is a hollow shell, of any thickness but with a hole in the middle,
and the material in the shell is evenly distributed (homogeneous, or of uniform
density), then there is zero gravity anywhere inside the shell.
Zero, because the electric field inside a charged hollow sphere is zero. This is due to the Gauss's law and symmetry of the charged hollow sphere, which results in no net electric field inside the sphere.
The electric field inside a charged hollow sphere is zero because the net contribution from the charges on the inner surface of the sphere cancels out due to symmetry. This means that the field created by the positive charges is equal and opposite to the field created by the negative charges, resulting in a net field of zero inside the sphere.
Inside a hollow charged sphere, the electric potential is constant and zero throughout the interior of the sphere. This is because the electric field due to the charges on the outer surface cancels out within the hollow region, resulting in no work done on a test charge to move it within the hollow sphere.
If the sphere is conducting, all the charge is distributed uniformly on the outer surface of the sphere.
If the net charge enclosed by a surface is zero then the field at all points on the surface is not zero because gauss's law states that if the charge enclosed by a surface is zero then the flux through the surface is zero which depends upon the magnitude of field and the angle that it makes with the area vector at each point and so it is not necessary that the field will be zero at all points of the surface.

In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
If the net charge enclosed by a surface is zero then the field at all points on the surface is not zero because gauss's law states that if the charge enclosed by a surface is zero then the flux through the surface is zero which depends upon the magnitude of field and the angle that it makes with the area vector at each point and so it is not necessary that the field will be zero at all points of the surface.
The distribution of the electric field inside a sphere is uniform, meaning it is the same at all points inside the sphere.
The electric field inside a hollow conductor is zero.
The electric field inside a charged sphere is uniform and directed radially towards the center of the sphere.
The electric field inside a uniformly charged sphere is zero.
A hollow magnetic sphere is a sphere made of magnetic material with an empty space inside. Its properties include the ability to attract and repel other magnetic objects, as well as the ability to create a magnetic field. Some applications of a hollow magnetic sphere include use in magnetic resonance imaging (MRI) machines, magnetic levitation systems, and as a component in magnetic sensors and actuators.
