A) The collision may be perfectly inelastic
B) The collision may be inelastic
C) The collision may be elastic
D) The collision must be inelastic
Correct Answer: D
Solution :
In the process of collision, the electron (because of very low mass in comparison to hydrogen atom) can loose upto 10 eV. 10 eV is sufficient to ionise the hydrogen atom or excite to higher excited state from first excited state. Hence, the collision can be elastic, inelastic or perfectly inelastic.You need to login to perform this action.
