Two metallic spheres have same radii One of them is solid and the other is hollow. They are charged to the same potential. The charge on the former is `q_(1)` and that of the latter is `q_(2)`. We have

Options

A. `q_(1)=q_(2)`
B. electrostatic field inside both of them to be zero
C. electrostatic potential in both the spheres at an inside point same as that at the surface
D. charge in both is effectively assumed to be concentrated at the centre for field strength at an external point

Explanation

To solve the problem, we need to analyze the properties of the two metallic spheres: one solid and one hollow, both having the same radius and charged to the same potential. We will derive the relationships between their charges and capacitance.

### Step-by-Step Solution:

1. **Understand the Concept of Capacitance**:
The capacitance \( C \) of a sphere is given by the formula:
\[
C = \frac{Q}{V}
