Let r, v and E are the radius of the orbit, speed of the electron and the total energy of the electron respectively. Which of the following quantities are proportional to the quantum number .n. ?

A

`rE`

B

`ur`

C

`upsilon/E`

D

`r/E`

Text Solution

Verified by Experts

The correct Answer is:
B, C
`upsilon = (2.188xx10^(-8))/(n)` cm/sec
`r= n^2 xx 0.529 xx 10^(-8) cm , E=-(2.18 xx 10^(-18))/(n^2)`
these relations shown that `upsilonr and (upsilon)/(E)` will be proportional to be principal quantum number n.
