The gyro magnetic ratio of an electron in an H atom according to Bohr model is

Options

A. `9xx10^(10)` C/kg
B. `8.8xx10^(10)` C/kg
C. `8.5 xx10^(11)` C/kg
D. `8.2 xx10^(10)` kg

Answer

A

Explanation

The gyromagnetic ratio of an electron in the H atom
=magnetic moment of the electron `(M_(0))/("Angular momentum of the electron")`
due to its orbital motion `L_(0)`
The magnetic moment of the electron due to its orbital motion is
`M_(0) =("evr")/(2)`
where v is the velocity of the electron moving in a circular orbit of radius the angular momentum of the electron due to its orbital motion is
As e and `m_(e )` are constant tehe gyromagnetic ratio is constant it is independent of the number of orbit
