If the energy of an electron in 3rd Bohr orbit is `-E`, what is the energy of the electron in (i) 1st Bohr orbit (ii) 2nd Bohr orbit ?

Explanation

To find the energy of an electron in the 1st and 2nd Bohr orbits given that the energy of an electron in the 3rd Bohr orbit is \(-E\), we can use the formula for the energy of an electron in the nth orbit according to Bohr's model:

\[ E_n = -\frac{13.6 \, Z^2}{n^2} \text{ eV} \]

Where:
- \(E_n\) is the energy of the electron in the nth orbit,
