The product of linear momentum and angular momentum of an electron of the hydrogen atom is proportional to `n^(x)`, where x is

Options

A. 0
B. 1
C. `-2`
D. `2`

Answer

A

Explanation

Linear momentum`=mv=(mcZ)/(137n)`
angular momentum=`(nh)/(2pi)`
Given, linear momentum`xx`angular momentum`propn^(x)`
`therefore (mcZ)/(137n)xx(nh)/(2pi)propn^(x)`
`n^(0)propn^(x) implies x=0`
