Q2.An electron with K.E. 5 eV is incident on a hydrogen atom in its ground state.The collision
(A) must be elastic
(B) may be partially elastic
(C) must be completely inelastic
(D) may be completely inelastic
Explain the solution.Rates are for sure.

I think, Since the energy is less than 13.6 X 3/4, the minimum energy required for a transition from ground state, the collision will be elastic.

the min energy that is required for an elastic collision is 13.6
an elastic collision will be possible only if the photon will have 13.6 eV
and so this collision isn't elastic
D)may be completely inelastic
