Bohr’s atomic model is applied to a particle of mass ‘ m ’ and charge ‘ q ’ moving in a plane under the influence of a transverse magnetic field ‘ B ’. The energy of the charged particle in the n t h level will be h = P l a n c k ' s c o n s t a n t
Options
- A2 n h q B / π m
- Bn h q B / 2 π m
- Cn h q B / 4 π m
- Dn h q B / π m
Correct answer
C. n h q B / 4 π m
Step-by-step solution
∵ T . E . = 1 2 m v 2 ∵ m v r = n h 2 h ⇒ m v m v q Β = n h 2 π ⇒ m v 2 = n h q B 2 π m ⇒ ∴ E = n h q B 4 π m
