JEE Mains · Physics · STD 12 - 12. atoms
Using Bohr's model, calculate the ratio of the magnetic fields generated due to the motion of the electrons in the \(2^{\text{nd}}\) and \(4^{\text{th}}\) orbits of hydrogen atom _______.
- A 8
- B 16
- C 32
- D 40
Answer & Solution
Correct Answer
(C) 32
Step-by-step Solution
Detailed explanation
The magnetic field at the center of a circular orbit is given by \(B = \dfrac{\mu_0 I}{2r}\). The equivalent current due to the revolving electron is \(I = \dfrac{e}{T} = \dfrac{ev}{2\pi r}\). Substituting \(I\) into the expression for \(B\), we get…
