Find the kinetic energy, potential energy and total energy in
first and second orbit of hydrogen atom if potential energy in first orbit is taken
to be zero.

Explanation

To find the kinetic energy, potential energy, and total energy in the first and second orbits of a hydrogen atom, we can follow these steps:

### Step 1: Calculate Total Energy in the First Orbit
The formula for the total energy \(E_n\) of an electron in the nth orbit of a hydrogen atom is given by:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
For the first orbit (\(n = 1\)):
