The velocity of an e in excited state of H-atom is `1.093 xx 10^(6)m//s`, what is the circumference of this orbit?

A

`3.32 xx 10^(-10)m`

B

`6.64 xx 10^(-10)m`

C

`13.30 xx 10^(-10)m`

D

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(n) = 2.18 xx 10^(8)//n cm//sec`
Where `n = 2`, Circum ference `= 2pi r_(n)`
