Q.
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 me], the first Bohr radius and ground state energy will be,
