S1 : Potential energy of the two opposite charge system increases with the decrease in distance.
S2 : When an electron make transition from higher orbit to lower orbit it's kinetic energy increases.
S3 : When an electron make transtition from lower energy to higher energy state its potential energy increases.
S4 : 11eV photon can free an electron from the 1stexcited state of He+ -ion.

Explanation
Solution
S1 : Potential energy of the two opposite charge system decreases with decrease in distance,
S4 : The energy of Ist excited state of He+ ion
= – 3.4 Z2 = – 3.4 × 22
– 13.6 eV.
