Which of the following products in a hydrogen atom are independent of the principal quantum number n? The symbols have their usual meanings

A

`vxxr`

B

`En`

C

`Er`

D

`vxxn`

Text Solution

Verified by Experts

The correct Answer is:
C, D
`v=(2piKe^(2))/(nh) :. vn=(2piKe^(2))/h`
`v_(n)` is independent of n.
Also `E prop 1/(n^(2)) and r prop n^(2)`
`:.` Er is independent of n.
