In a mixture of `H- He^(+)` gas (`He+ `is singly ionized He atom), `H` atom and `He+` ions are excited to their respective first excited state. 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 the of `He^(+)` lon is -

A

`(1)/(4)`

B

`(1)/(2)`

C

1

D

2

Text Solution

Verified by Experts

kinetic energy, `K prop Z^(2)`
`(K_(H))/(K_(He^(+))) = ((1)/(2)^(2) = (1)/(4)`
