The gyromagnetic ratio and Bohr magneton are given respectively by [Given e = charge on electron, m = mass of electron, h = Planck's constant].
Options
- Ae 2 ~m , eh 4 ~m
- Beh 4 ~m , e 2 ~m
- C2 ~m e , 4 ~m eh
- D4 ~m eh , 2 ~m e
Correct answer
A. e 2 ~m , eh 4 ~m
Step-by-step solution
As we know the formula gyromagnetic ratio (= L M ) ( angular momentum ( L )= n h 2 ) Magnetic moment(M) (=n ) Bohrmagneton (=n e h 4 m ) So, gyromagnetic ratio (= n h 2 n e h 4 m = e 2 m )
