The ground state energy of hydrogen atom is -13.6 eV. What are the kinetic and potential energies of the electron in this state ?

Explanation

To find the kinetic and potential energies of the electron in the ground state of a hydrogen atom, we can use the relationships between total energy, kinetic energy, and potential energy.

### Step-by-Step Solution:

1. **Understand the Total Energy**:
The total energy (E) of the electron in the ground state of a hydrogen atom is given as:
\[
E = -13.6 \, \text{eV}
