The graph of $\ln \left(\frac{R}{R_0}\right)$ versus $\ln A$ ($R=$radius of a nucleus and $A=$mass number) is

In Rutherford nuclear model of an atom, for a dynamically stable orbit in hydrogen atom, the orbit radius varies with the velocity of the electron as $\frac{1}{v^a},$ where $\alpha$ is, 
(Ignore radiation due to motion of electric charge)

A hydrogen atom is in a state with energy $-1.51\mathrm{eV}$. In the Bohr model, the angular momentum of the electron in the atom with respect to an axis at the nucleus, is $\left(\frac{h}{2\pi }=1.05\times {10}^{-34} \mathrm{J} \mathrm{s}\right)$

The potential energy of the electron in the first excited state of the hydrogen atom is

Wavelength, $\lambda$ is emitted when an atom moves from, $2E$ energy level to, $E$ energy level. If the transition takes place from, $\frac{5}{3}E$ energy level to, $E$ energy level, then the emitted wavelength will be

The series corresponding to lowest wavelength transition in $\mathrm{H}$ - atom.

If $R$ is Rydberg constant then, the shortest wavelength of the Balmer series of the hydrogen atom is:
