Question

Calculate the gyromagnetic ratio of electron.

(given e = 1.6 × 10–19C, Me = 9.1 × 10–31 kg)​

Answer 1

Explanation:

Magnetic moment μ=evr/2

Angular momentum L=mvr

Gyromagnetic ratio is the ratio of magnetic moment of the particle to its angular momentum.

∴ γ=

L

μ

=

mvr

evr/2

⟹ γ=

2m

Answer 2

Answer:

1.6 × 10 -19/2×9.1×10-31

=8.8 × 10 ^10 C Kg^-1
