In side a hollow isolated spherical shell-

Options

A. The gravitation potential is not zero
B. The gravitational field is not zero
C. The gravitational potential is same everywhere
D. The gravitational field is same everywhere

Answer

To solve the question regarding the gravitational field and potential inside a hollow isolated spherical shell, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Hollow Sphere**:
- A hollow isolated spherical shell means that the shell has mass distributed uniformly over its surface and there is no mass inside it.

**Hint**: Visualize the hollow sphere and remember that it has no mass in its interior.

2. **Gravitational Field Inside the Shell**:
- According to Newton's Shell Theorem, the gravitational field inside a hollow spherical shell is zero. This means that if you were to measure the gravitational field at any point inside the shell, it would be equal to zero.

**Hint**: Recall Newton's Shell Theorem which states that the gravitational field inside a hollow shell is zero.

3. **Gravitational Potential Inside the Shell**:
- The gravitational potential inside the hollow shell is constant at all points. While the gravitational field is zero, the potential does not equal zero; it is a constant value throughout the interior of the shell.

**Hint**: Remember that gravitational potential can be constant even when the gravitational field is zero.

4. **Conclusion**:
- Therefore, we conclude that:
- The gravitational field inside the hollow shell is zero.
- The gravitational potential inside the hollow shell is constant and not equal to zero.

**Hint**: Summarize the key points: gravitational field = 0, gravitational potential = constant (not zero).

### Final Answer:
- The gravitational field inside the hollow isolated spherical shell is zero.
- The gravitational potential inside the hollow isolated spherical shell is constant and not equal to zero.
