In going from the surface of a charged conducting sphere towards the centre of the sphere the electric field

Options

A. increases
B. decreases
C. remains the same as on the surface
D. remains zero at every place

Answer

To solve the question regarding the behavior of the electric field as one moves from the surface of a charged conducting sphere towards its center, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Charged Conducting Sphere**:
- A conducting sphere allows charges to move freely. When the sphere is charged, the excess charge resides on its outer surface due to the repulsion between like charges.

**Hint**: Remember that in conductors, charges redistribute themselves to minimize repulsion.

2. **Electric Field Inside Conductors**:
- One of the fundamental properties of conductors in electrostatic equilibrium is that the electric field inside a conductor is zero. This means that if you are inside the conducting material itself, there will be no electric field present.

**Hint**: Recall Gauss's Law, which states that the electric field inside a conductor in electrostatic equilibrium is zero.

3. **Moving Towards the Center**:
- As you move from the surface of the charged conducting sphere towards the center, you are moving into a region where the electric field is already established as zero. Therefore, regardless of how far you move inward, the electric field remains zero.

**Hint**: Consider that the electric field is a vector quantity and is influenced by the distribution of charge. In this case, the charge is only on the surface.

4. **Conclusion**:
- Since the electric field inside the conducting sphere is zero, it remains zero at every point as you move from the surface to the center of the sphere.

**Hint**: Think about the implications of having no net charge inside a closed surface when applying Gauss's Law.

### Final Answer:
The electric field in going from the surface of a charged conducting sphere towards the center of the sphere remains zero at every point.
