The magnetic moment of an electron due to its orbital motion is proportional to (where $n$ is the principal quantum number).

Mention the value of the Rydberg constant with its unit.

It is found experimentally that $13.6 \; eV$ energy is required to separate a hydrogen atom into a proton and an electron. Compute the orbital radius and the velocity of the electron in a hydrogen atom.

The wavelengths involved in the spectrum of deuterium $(_1^2D)$ are slightly different from that of hydrogen spectrum,because

Using Bohr's atomic model,derive an equation for the radius of the $n^{th}$ orbit of an electron.

In a system, a particle $A$ of mass $m$ and charge $-2q$ is moving in the nearest orbit around a very heavy particle $B$ having charge $+q$. Assuming Bohr's model of the atom to be applicable to this system, the orbital angular velocity of the particle $A$ is
