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). Assume that the Bohr model of atom is exactly valid.
The ratio of the kinetic energy of the n=2 electron for the H atom to that of He+ ion is –
a. 1/4
b. 1/2
c. 1
d. 2
