\( \mathbf{S}_{1} \) : Potential energy of the two opposite charge system increases with the decrease in distance.
\( \mathbf{S}_{2} \) : When an electron make transition from higher orbit to lower orbit its kinetic energy increases.
\( \mathbf{S}_{3} \) : When an electron make transtition from lower energy to higher energy state its potential energy increases.
\( \mathbf{S}_{4}: 11 \mathrm{eV} \) photon can free an electron from the \( 1^{\text {st }} \) excited state of \( \mathrm{He}^{+} \)-ion.
