The magnetic moment of an electron (e) revolving in an orbit around nucleus with an orbital angular momentum is given by:
Options
- A_L= e L 2 m
- B_L=- e L 2 m
- C_l=- e L m
- D_l= 2 e L m
Correct answer
A. _L= e L 2 m
Step-by-step solution
As M = IA | M |= e 2 R v R ^2 [ I = Q T = e 2 R V ] | M |= 1 2 e v R | M |= mvR 1 e 2 ~m | M |= eL 2 ~m | M |=- e L 2 ~m [ Here M and L will always be opposite]
