What is the magnetic moment of orbiting electron in simple hydrogen atom?
Assume charge of electron, mass of electron and orbital angular momentum of electron
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
When an electron is orbiting around the hydrogen nucleus then total angular momentum, L=mevr and magnetic moment, μ=iA=eTπr2 ..1, here r is the radius of the orbit, sp the time period, T=2πrv⇒2πrmerL=2meπr2L ...2, from…
