A partical of charge equal to that of an electron `(-e)` and mass `208` times the mass of electron `(called a mu - mason)` moves in a circular orbit around a nucleus of charge `+ 3e`. (Take the mass of the nucleus to be infinate.) Assume the Bohr 's model of the atom is applicable to this system.
a drive and expression for the radius of the nth Bohr orbit.
b Find the value of `n` for which the redius of the bohr orbit for the hydrogen atom.
c Find the wavelength of the radition emitted when the `mu` -meson jumps from the third orbit to the first orbit. (Rydberg's constant`= 10967800 m)`
