A gyromagnetic ratio of the electron revolving in a circular orbit of hydrogen atom is 8.8xx10^(10)C kg^(-1). What is the mass of the electron? Given charge of the electron =1.6xx10^(-19)C.

Answer»

`1 xx 10^(-29)kg`
`0.1 xx 10^(-29) kg`
`1.1 xx 10^(-29) kg`
`1//11 xx 10^(-6)T`

Solution :`(MU)/(L) = (e)/(2m)`
`m = (e)/(2(mu//L)) = (1.6 xx 10^(-19))/(2 xx 8.8 xx 10^(10)) = (1)/(11) xx 10^(-29) kg`
