In Rutherford experiment, for head-on collision of $\alpha -$particles with a gold nucleus, the impact parameter is

Energy of an electron in the second orbit of hydrogen atom is $E_2.$ The energy of electron in the third orbit of $H{e}^{+}$will be

The total energy of an electron revolving in the second orbit of the hydrogen atom is

The period of revolution of an electron in the ground state of the hydrogen atom is $T$. The period of revolution of the electron in the first excited state is

Frequency of revolution of an electron revolving in n^th orbit of H-atom is proportional to

A hydrogen atom in ground state absorbs $10.2 eV$ of energy. The orbital angular momentum of the electron is increased by

Angular momentum of an electron in hydrogen atom is $\frac{3 h}{2\pi }$ ($h$ is the Planck's constant). The K.E. of the electron is
