Let the potential energy of a hydrogen atom in the ground state be zero. Then, its energy in the first excited state will be  

If the ionisation energy of a hydrogen like Bohr atom is 4 Rydberg, then the wavelengths of radiation emitted when the electron jumps from first excited state to the ground state and the radius of the first orbit of this atom are:

The ratio of areas within the electron orbits for the first excited state to the ground state for hydrogen atom is

The innermost orbit of the hydrogen atom has a diameter of $$1.06 A^o$$. What is the diameter of the tenth orbit?

Find an expression for de Broglie wavelength for an electron in the $$n^{th}$$ orbit of the Bohr model of the hydrogen atom and hence find its value when the electron is in n = 4 level.
Take radius of nth orbital of Bohr's model of H-atom; $$r_n = (53 \ n^2) $$ pm

A satellite of mass $$10\ kg$$ orbites around the earth once every $$2\ h$$ in an orbit of radius $$8000\ km$$. If Bohr's angular momentum is assumed to be applicable to the satellite, the quantum number of the orbit of the satellite is

According to Bohr modal, magnetic field at the centre (at the nucleus) of a hydrogen atom due to the motion of electron in $$n^{th}$$ orbit is proportional to:

The $$H_{a}$$-line of hydrogen

The wave number of first line in Balmer series of hydrogen spectrum is (Rydberg constant, $$R_H = 109,687 \,cm^{-1}$$) nearly
