Inside a uniform spherical shell (This question has Multiple correct answers)A. The gravitational potential is zero.B. The gravitational field is zero.C. The gravitational potential is the same everywhere.D. The gravitational field is the same everywhere.

The correct answers are:

C. The gravitational potential is the same everywhere.
D. The gravitational field is the same everywhere.

Inside a uniform spherical shell, the gravitational potential is constant throughout the interior. This means that at any point inside the shell, the gravitational potential is the same regardless of the position within the shell. Therefore, option C is correct.

In terms of the gravitational field, inside a uniform spherical shell, the gravitational field is zero. This is because the gravitational forces from all parts of the shell cancel out exactly at any point inside. The shell acts as if all its mass is concentrated at its center, resulting in no net gravitational field inside the shell. Therefore, option D is also correct.
