Question

A particle of mass $m$ moves in a circular orbit in a central potential field $U(r)=\frac{1}{2} k r^2$. If Bohr's quantization conditions are applied, radii of possible orbitals and energy levels vary with quantum number $n$ as

Select the correct option:

$r_n \propto n, E_n \propto n$

$r_n \propto \sqrt{n}, E_n \propto n$

$r_n \propto \sqrt{n}, E_n \propto \frac{1}{n}$

$r_n \propto n^2, E_n \propto \frac{1}{n^2}$

✓ Correct! Well done.
