The radius of the first permitted Bohr orbit for the electron in a hydrogen atom equals $0.53\text{A˚}$ and its ground state energy equals $-13.6\text{eV}$. If the electron in the hydrogen atom is replaced by a muon (${\mu }^{-}$) [charge same as electron and mass $207m_e$ ], the first Bohr radius and ground state energy will be ($m_e$ represents the mass of an electron):
