Class 12 NEET Physics Atoms and Nuclei Questions Part 2

The radius of the first permitted Bohr orbit for the electron, in a hydrogen atom equals 0.51A and its ground state energy equals −13.6‌eV. if the electron in the hyrogen atom is replaced by muon (µ−)[charge same as electron and mass 207me ], the first Bohr radius and ground state energy will be :
