List of top Physics Questions on Bohr Model Of The Hydrogen Atom asked in AP EAPCET

The energy of an electron in Bohr's hydrogen atom is \(-3.4\,eV\). The angular momentum of the electron is

Suppose an electron is attracted towards the origin by a force \( K/r \), where K is a constant and r is the distance of the electron from the origin. By applying Bohr model to this system, the radius of the \( n^{th} \) orbit of the electron is found to be \( r_n \), and the kinetic energy of the electron to be \( T_n \), then which of the following is true?

An electron is moving in an orbit of hydrogen atom in which there can be a maximum of six transitions. Another electron is moving in another orbit of hydrogen atom in which there can be a maximum of three transitions. The ratio of the velocity of electrons in these two orbits is:
