Calculate the velocity of an electron in the first Bohr orbit of a hydrogen atom

A

(a) `2.18xx10^(5)` m/s

B

(b) `2.18xx10^(6)` m/s

C

(c) `2.18xx10^(-18)` m/s

D

(d) `2.18xx10^(-9)` m/s

Text Solution

Verified by Experts

The correct Answer is:
B

From Bohr's theory, `v=2.18xx10^(6)xxZ/n m//s
=2.18xx10^(6)xx1/1=2.18xx10^(6)m//s`
