Question
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 1st excited state of He+ -ion.
S2 : When an electron make transition from higher orbit to lower orbit it′s kinetic energy increases.
