In a mixture of H – He+ gas (He+ is singly ionized He atom), H atoms and He+ ions are excited to their respective first excited states. Subsequently, H atoms transfer their total excitation energy to He+ ions (by collisions). Assuming that the Bohr model of atom is applicable, answer the following questions.
The ratio of the potential energy of the n = 2 electron for the H atom to that of He+ ion is :
- 1/4
- 1/2
- 1
- 2
Answer
(A) 1/4
