In a hypothetical Bohr hydrogen atom, the mass of the electron is doubled. The energy E0 and radius r0 of the first orbit will be (a0 is the Bohr radius) –

A

E0 = –27.2 eV; r0 = a0

B

E0 = –13.6 eV; r0 = a0/2

C

E0 = –27.2 eV; r0 = a0/2

D

E0 = –13.6 eV; r0 = a0

Answer

E0 = –27.2 eV; r0 = a0/2
