In a hypothetical Bohr hydrogen, the mass of the electron is doubled. The energy \[{{E}_{0}}\]and the radius \[{{r}_{0}}\]of the first orbit will be (\[{{a}_{0}}\]is the Bohr radius) [Roorkee 1992]

\[{{E}_{0}}=-\ 27.2\ eV;\ {{r}_{0}}={{a}_{0}}\]

\[{{E}_{0}}=-\ 27.2\ eV;\ {{r}_{0}}={{a}_{0}}/2\]

\[{{E}_{0}}=-13.6\ eV;\ {{r}_{0}}={{a}_{0}}/2\]

\[{{E}_{0}}=-13.6\ eV;\ {{r}_{0}}={{a}_{0}}\]
