The electron in the first orbit of hydrogen has velocity `2.18xx10^(6)` m/s. If radius of first orbit is 0.53 Å then orbital current in the orbit is

A

0.41 mA

B

1.04 mA

C

1.84 mA

D

2.4 mA

Text Solution

Verified by Experts

The correct Answer is:
B
`I=(ev)/(2 pi r)=(1.6xx10^(-19) xx2.18xx10^(6))/(2xx3.14xx0.53xx10^(-10))`
`=1.04` mA
