If the PE of an electron in the first Bohr orbit of H is zero , the total energy of the electron in second Bohr orbit is

Options

A. `23.8 eV`
B. `-23.8 eV`
C. `-3.4 eV`
D. `3.4 eV`

Explanation

To find the total energy of the electron in the second Bohr orbit of hydrogen when the potential energy (PE) of the electron in the first orbit is zero, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Energy in Bohr Model**:
In the Bohr model of the hydrogen atom, the total energy (E) of an electron in the nth orbit can be calculated using the formula:
\[
E_n = -\frac{13.6 \, \text{eV}}{n^2}
