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`

Answer» Correct Answer - A
`K.E =-T.E=13.6Z^(2)/n^(2)eV`
