A particle of charge ' q ' and mass ' m ' moves in a circular orbit of radius ' r ' with angular speed ' '. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on

Options

  1. Aand q
  2. Band m
  3. Cq and m
  4. D, q and m

Correct answer

C. q and m

Step-by-step solution

Angular momentum ( L )= I = mr ^2 Magnetic moment (M)= r^2 q f= r^2 q 2 = 1 2 q r^2 M L = q 2 ~m
