Calculate the separation between the particles of a system in the ground state, the corresponding binding energy and wavelength of first line in Lyman series if such a system is a positronium atom consisting of an electron and a positron revolving around their common Centre of masses.
[ Assuming that Bohr model of the atom is applicable to this system. ]
- \(1.06 \mathrm{~A}, 6.8 \mathrm{eV}, 0.243 \mu \mathrm{~m}\)
- \(2.85 \mathrm{~A}^{\mathrm{A}}, 2.53 \mathrm{eV}, 0.65 \mu \mathrm{~m}\)
- \(1.86 \mathrm{~A}^{\mathrm{d}}, 6.8 \mathrm{eV}, 0.65 \mu \mathrm{~m}\)
- \(1.86 \mathrm{~A}, 2.53 \mathrm{eV}, 0.243 \mu \mathrm{~m}\)
Answer
(A) 1.06 ~A , 6.8 eV , 0.243 ~m
