उत्तर
a and b
Explanation:
Angular momentum of electron (L) = nh/2π
Magnetic moment of electron M = neh/4πm
Gyromagnetic ratio = magnetic moment/angular momentum
2πneh/4πnhm
= e/2m
= constant
It is independent of the orbit in which the electron is revolving.
Since e is negative, the geomagnetic ratio is negative.
