Bohr model is a system consisting of small, dense nucleus surounded by orbting electrons. The electrons travel in defined circular orbits around the nucleus for which orbital angular momentum is an itnegral multiple of `h/(2pi)`. While rotating in allowed orbits the electrons does not raidate energy. Electromagneitc radiations are emitted when the electrons jumps from a higher orbit `(E_(n_i))` to a lower orbit `(E_(n_f))`
Allowed energy of hydrogen atom in the `n^(th)` orbit is:

A

`(me^4)/(8epsilon_0^2n^2h^2)`

B

`-(me^4)/(8epsilon_0^2n^2h^2)`

C

`-(me^4)/(8epsilon_0^2n^2h^3)`

D

`(me^4)/(8epsilon_0^2n^2h^3)`
