A hydrogen atom undergoes the transition $n = 2 \to 1$ . The ratio of final to initial magnetic field due to the motion of the electron at the nucleus will be

Options:

Answer:

Solution:

$B \propto \frac{v}{r ^{2}} \propto \frac{1/ n}{n ^{4}} = n^{- 5}$ . Hence $\frac{B _{f}}{B _{i}} = (\frac{2}{1})^{5} = 32 : 1$ .
