The ground state energy of hydrogen atom is $-13.6 ev$ what are the kinetic and potential energies of the electron of the electron in this state ?

Question

$\begin{array}{1 1} K.E=-27.2\;ev ;P.E=-13.6\;ev \\K.E=-13.6\;ev ;P.E=-27.2\;ev \\ K.E=13.6\;ev ;P.E=27.2\;ev \\ K.E=13.6\;ev ;P.E=-27.2\;ev \end{array}$
