An electron moves in Bohr orbit. The magnetic field at the centre is proportional to

In hydrogen atom, radius of the smallest orbit of the electron is a₀, the radius of the third orbit is

An electron jumps from the 4^th orbit to the 2^nd orbit of hydrogen atom. Given the Rydberg’s constant R = 10⁷ m-1. The frequency in Hz of the emitted radiation is (c = 3x10⁸ m/s)

$\lambda_1$ is the wavelength of series limit of Lyman series, $\lambda_2$ is the wavelength of the first line of Lyman series and $\lambda_3$ is the series limit of the Balmer series. Then the relation between $\lambda_1$, $\lambda_2$ and $\lambda_3$ is

Bohr model is applied to a particle of mass $'m'$ and charge $'q'$ is moving in a plane under the influence of a transverse magnetic field $'B'$. The energy of the charged particle in the $nth$ level will be ($h =$ Planck's constant)

If the electron in a hydrogen atom jumps from an orbit with level $n_{1} =2$ to an orbit with level $n_{2} =1$ the emitted radiation has a wavelength given by

If an electron is revolving around the hydrogen nucleus at a distance of $ 0.1 \,nm $ , what should be its speed ?
