If an electron is revolving around the hydrogen nucleus at a distance 0.1 mm. What should be its speed

A

`2.188xx10^(6)` m/s

B

`1.094 xx10^(6)` m/s

C

`4.376 xx10^(6)` m/s

D

`1.59xx10^(6)` m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(n)=e^(2)/(2 epsi_(0) nh)`
`:. V_(1)=((1.6xx10^(-19))^(2))/(2xx8.85xx10^(-12)xx1xx6.63xx10^(-34))`
`=2.188xx10^(6) m//s`.
