The electron in a hydrogen atom moves in a circular orbit of radius `5 xx 10_(-11) m` with a speed of `0.67 xx 10_(8) m//s` Then

Options

A. the frequency of revolutions of the electron is `6 xx 10^(-15) rev//s`
B. the electron carries `-1.6 xx 10(-19)C` around the loop
C. the current in the orbit is `0.96 mA`
D. the current flow in the opposite direction to the direction of motion of electron

Explanation

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(0.6xx10^(6)xxpi)/(2pixx5xx10^(-11))=6xx10^(15)rev//s`
`i=6xx10^(15)xx1.6xx10^(-19)`= `0.96 xx 10^(-3)A = 0.96 mA`
therefore Hence, all the options are correct
