The energy of the electron in the ground state of hydrogen atom is `-13.6 eV`. Find the kinetic energy and potential energy of electron in this state.

Explanation

To solve the problem, we need to find the kinetic energy (KE) and potential energy (PE) of the electron in the ground state of a hydrogen atom, given that the total energy (E) is -13.6 eV.

### Step-by-Step Solution:

1. **Understand the Relationship Between Energies**:
- In a hydrogen atom, the total energy (E) of the electron is related to its kinetic energy (KE) and potential energy (PE) as follows:
\[
E = KE + PE
