The radius of innermost electron orbit of a hydrogen atom is `5.3xx10^(-11)m`. What is the radius of orbit in second excited state?

Explanation

To find the radius of the orbit in the second excited state of a hydrogen atom, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Electron Orbits**:
- The innermost electron orbit corresponds to the ground state (n=1).
- The first excited state corresponds to n=2.
- The second excited state corresponds to n=3.
