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 two metallic spheres: one solid and one hollow, both having the same radius and charged to the same potential. We will denote the charge on the solid sphere as \( q_1 \) and the charge on the hollow sphere as \( q_2 \).

### Step-by-Step Solution:

1. **Understanding the Potential of Spheres:**
- The potential \( V \) of a charged sphere is given by the formula:
\[
V = \frac{k \cdot Q}{R}
