The velocity of the electron in the first Bohr's orbit is `2.181xx10^(6) m//s`. The linear velocity of electron in third orbit is

A

`72.7xx10^(5) m//s`

B

`2.77xx10^(5) m//s`

C

`7.27xx10^(5) m//s`

D

`5.57xx10^(5) m//s`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(n)=v_(1)/n`
`:. v_(3)=v_(1)/3`
`=(2.181xx10^(6))/3=7.27xx10^(5)` m/s
