Question
In the Bohr model of a hydrogen atom, the centripetal force is furnished by the coulomb attraction between the proton and the electron. If a0 is the radius of the ground state orbit, m is the mass, e is the charge on the electron and λ0 is the vacuum permittivity, the speed of the electron in first excited state is :-
Options
A.
B.
C.
D.
Solution
In ground state,
v =
∵ v ∝
∴ velocity in first excited state (n = 2)
v2 =
v =
∵ v ∝
∴ velocity in first excited state (n = 2)
v2 =
