The radius of the first permitted Bohr orbit, for the electron, in a hydrogen atom equals 0.51 Å and its ground state energy equals
–13.6 eV. If the electron in the hydrogen atom is replaced by muon ( $μ$ –) [charge same as electron and mass 207 $m_{e}$ ], the first Bohr radius and ground state energy will be,
