If velocity of an electron in 1st orbit ...

If velocity of an electron in 1st orbit of H atoms is V , what will be the velocity in 3rd orbit of `Li^(2+)` ?

A

`V`

B

`V//3`

C

`3V`

D

`9V`

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(n)=2.188xx10^(6)xx(Z)/(n)m//sec`
`(V_(3)(Li^(2+)))/(V_(1)(H))=(Z_(3)//n_(3))/(Z_(1)//n_(1))=(3//3)/(1//1)" "V(Li^(2+))=V`
