In hydrogen atom , the electron moves in an orbit of radius 0.5 Å , making `10^(16)` cps . Calculate magnetic moment associated with the orbital motion of electron ?

Explanation

M = `ixxA`
=` q xx f xx pir^(2)`
= `1.6 xx 10^(-19) xx 10^(16) xx 3.14 xx 25 xx 10^(-22)`
`= 1.6 x 3.14 xx 25 xx 10^(-25)`
`= 125. 6 xx 10^(-25) A m^(2)`
`= 1.26 xx 10^(-23) A m^(2)`
