What is the ratio of the time periods `(T_1//T_2)` on second orbit of H atom to 3rd orbit of `He^+`

A

`8//27`

B

`32//27`

C

`27//32`

D

`27//8`

Text Solution

Verified by Experts

The correct Answer is:
B
`(T_1)/(T_2) = (n_1^3)/(z_1^2)xx (z_2^2)/(n_2^3) implies (2^3)/(1^2) xx (2^2)/(3^3) implies (32)/(27)`
