A particle of charge q and mass m moves in a circular orbit of radius r with angular speed ω. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on (a) ω and q (b) ω, q and m (c) q and m (d) ω and m |

Answer» Correct Answer is: (c) q and m The effective current is i = q . ω/2π and the area is A = πr2. The magnetic moment is μ = Ai = qωr2. The angular momentum is L = Iω mr2ω. ∴ μ/L = q/2m. |
