The electron in a hydrogen atom moves in...

The electron in a hydrogen atom moves in circular orbit of radius `5xx10^(-11)m` with a speed of `0.6pixx10^(6)m//s` then

A

the frequency of the electron is `6xx10^(15)rev//s`

B

the electron carries `-1.6xx10^(-19)C` around the loop

C

the current in the orbit is `0.96mA`

D

the current flow is in the opposite direction to the direction of the motion of electron

Text Solution

Verified by Experts

Electric current at a point on the circle
`i=fe`, where `f=`frequency `=(omega)/(2pi)=(v)/(2pir)=(0.6xx10^(6)xxpi)/(2pixx5xx10^(-11))=6xx10^(15)rev//s`
`i=6xx10^(15)xx1.6xx10^(-19)=0.96xx10^(-3)A=0.96mA`
