If `a_(0)` is the Bohrs the radius of the n=2 electronic orbit in triply ionized beryllium is

Options

A. `4a_(0)`
B. `a_(0)`
C. `a_(0)//4`
D. `a_(0)//16`

Explanation

To find the radius of the n=2 electronic orbit in triply ionized beryllium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We need to find the radius of the n=2 electronic orbit in triply ionized beryllium (Be³⁺). The atomic number (Z) of beryllium is 4.

2. **Use the Formula for the Radius**: The radius of the nth electronic orbit in a hydrogen-like atom is given by the formula:
\[
