The mass number and the volume of a nucleus is $M$ and $V$ respectively. If the mass number is increased to $2 M$ then the volume is changed to

In the hydrogen atom spectrum, let $E_1$ and $E_2$ are energies for the transition $n=2\to n=1$ and $n=3\to n=2$ respectively. The ratio $E_2/E_1$ is

A hydrogen atom in the ground state absorbs, $∆E$ amount of energy. If the orbital angular momentum of the electron is increased by $\frac{h}{2\pi }$($h=$ Plank constant), then the magnitude of $\Delta E$ is

If the light from Balmer series of hydrogen is used to eject photoelectrons from a metal, then the maximum work function of the metal can be

A hydrogen atom emits a photon corresponding to an electron transition from $n=5$ to $n=1.$ If $R$ is the Rydberg constant, then the wavelength of emitted photon is
