An electron of energy `11.2 eV` undergoes an inelastic collision with a hydrogen atom in its ground state [Neglect recoiling of atom as `m_(H) gt gt m_(e)]`. Then is this case

Options

A. The outgoing electron has energy 11.2eV
B. The entire energy is absorbed by H atom and the electron stopes
C. 10.2 eV of the incident electron energy is absorbed by the H atom and the electron would comeout with 1.0 eV energy
D. None of the above.

Answer

C
