A muonic hydrogen atom is formed when a muon (a particle with a mass approximately 207 times that of an electron but the same charge) replaces the electron. Considering Bohr's model, what is the ratio of the ionization energy of muonic hydrogen to that of regular hydrogen?

According to Bohr's model, an electron transitioning from the n=4 to n=2 state in a hydrogen-like ion emits a photon with a wavelength of 486 nm. What is the atomic number (Z) of this ion?

Consider a hypothetical universe where the electrostatic force between two charges is proportional to $1/r^3$ instead of $1/r^2$. According to the Bohr model adapted for this universe, how would the radius of the nth orbit ($r_n$) depend on n?

In the Bohr model, the ratio of the kinetic energy (K) to the potential energy (U) of an electron in the nth orbit is:
