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, given that the potential energy (PE) of the electron in the first Bohr orbit is zero, we can follow these steps:

### Step 1: Understand the relationship between total energy and potential energy
In the Bohr model, the total energy (E) of an electron in a given orbit is related to its potential energy (PE) by the equation:
\[ E = \frac{PE}{2} \]
This means that the total energy is always negative and is half of the potential energy.

### Step 2: Calculate the total energy in the first orbit
