When a hydrogen atom is excited from ground state to first excited state thenA. Its kintic energy increases by `10.2 eV`B. Its kinetic energy decreases by `10.2 eV`C. It potential energy increases by `20.4 eV`.D. Its angular momentum increases by `1.05 xx 10^(34) J-s` |

Answer» Correct Answer - B::C::D `|DeltaK| = 13.6[(1)/(1^(2)) - (1)/(2^(2))] = 10.2 eV` ltbr gt `|DeltaU| = 27.2 [(1)/(1^(2)) - (1)/(2^(2))] = 20.4eV` `DeltaL = (2h)/(2pi) - (h)/(2pi) = (h)/(2pi)` |
