Question:

The kinetic energy of an electron in the ground state of hydrogen atom is 13.6 eV. The potential energy (P.E) and total energy (E) of electron in this state is:

Options:

$P.E=-13.6 eV, E=27.2 eV$

$P.E=-13.6 eV, E=-27.2 eV$

$PE= +27.2 eV, E=-13.6 eV$

$P.E=-27.2 eV, E=-13.6 eV$

Correct Answer:

$P.E=-27.2 eV, E=-13.6 eV$

Explanation:

The correct answer is Option (4) → $P.E=-27.2 eV, E=-13.6 eV$
