The radius of the first permitted Bohr orbit, for the electron, in a hydrogen atom equals $\displaystyle 0.51 \AA$ and its ground state energy equals -$\displaystyle 13.6$ eV. If the electron in the hydrogen atom is replaced by muon $\displaystyle \left(\mu^{-}\right)$ [charge same as electron and mass $\displaystyle 207 \mathrm{~m}_{\mathrm{e}}$ ], the first Bohr radius and ground state energy will be
