1. The radius of the first permitted Bohr orbit for the electron, in a hydrogen atomequals 0.51 Å and its ground state energy equals −13.6 eV. If the electron in the hydrogen atomis replaced by muon (μ−1 ) [Charge same as electron and mass 207 me ], the first Bohr radius and ground stateenergy will be
