Ratio of velocity of electron in 5^(th) ...

Ratio of velocity of electron in `5^(th)` excited state and `3^(rd)` energy level for `He^(+)` atom is

A

`(1)/(4)`

B

`(1)/(6)`

C

`(1)/(3)`

D

`(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`(V_(6))/(V_(3)) = (Z)/(n_(6)) xx (n_(3))/(Z) = (n_(3))/(Z) = (n_(3))/(n_(6)) = (3)/(6) = (1)/(2)`
