Question

If the magnetic moment of an electron revolving in an orbit of radius 0.4 Å is 9 × 10^-24 A∙m² then find the linear momentum of the electron in that orbit. (e/m = 1.76 × 10¹¹ C/kg]

Answer 1

Data: r = 0.5 Å = 5 × 10^-11 m, I = 1.1 × 10^-3 A,

x = 100 Å = 10^-8 m, \(\cfrac{\mu_0}{4\pi}\) = 10^-7 T∙m/A
