Inside a uniform spherical shell : (a) the gravitational field is zero (b) the gravitational potential is zero (c) the gravitational field is same everywhere (d) the gravitational potential is same everywhere (e) all of the above Choose the most appropriate answer from the options given below :

1. (1) (a), (c) and (d) only
2. (2) (e) only
3. (3) (a), (b) and (c) only
4. (4) (b), (c) and (d) only

Correct answer: (1) (a), (c) and (d) only

Solution

Inside a uniform spherical shell, the gravitational field is zero due to the symmetry of the mass distribution, meaning that gravitational forces from all parts of the shell cancel out. The gravitational potential, however, is constant throughout the interior, making it the same everywhere, but it is not zero. Therefore, options (a), (c), and (d) are correct.
