The net charge given to an isolated conducting solid sphere :

Options

A. must be distributed uniformly on the surface
B. may be distributed uniformly on the surface
C. must be distributed uniformly in the volume
D. may be distributed uniformly in the volume.

Answer

To solve the question regarding the net charge given to an isolated conducting solid sphere, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Nature of the Sphere**:
- We need to identify that we are dealing with a conducting solid sphere. Conductors allow charges to move freely on their surface.

2. **Charge Distribution in Conductors**:
- When a net charge is given to a conducting sphere, the charge does not remain within the volume of the sphere. Instead, it redistributes itself on the surface of the sphere.

3. **Uniform Distribution**:
- The charge on the surface of a conducting sphere is distributed uniformly. This is due to the repulsive forces between like charges, which causes them to spread out evenly on the surface.

4. **Internal Charge Condition**:
- Inside the conducting sphere, the electric field is zero when in electrostatic equilibrium. This means that any excess charge resides entirely on the surface, and the interior remains neutral.

5. **Conclusion**:
- Therefore, the net charge given to an isolated conducting solid sphere is uniformly distributed over its surface.

### Final Answer:
The net charge given to an isolated conducting solid sphere is distributed uniformly on its surface.
