    This is a Multiple Choice Questions as classified in NCERT Exemplar

    Answer- (a)

    Explanation -Total energy in ground state collide elastically Is 213.6eV= 27.2eV

    When a electron excite from ground state to first excited state then

    Energy is =-13.6/22= 3.4eV+13.6 (ground state energy) eV = 17.0 eV

    So net energy is 27.2-17 =10.2eV
