Electrons bound to the nucleus/ Bohr hypothosis

[Jason Gomez]

Question:
If we assume that an electron is bound to the nucleus (assume a H atom) in a circular orbit, then the Coulomb force is equal to the centripetal force:
mv^2/r= ke^2/r^2
In the Bohr hypothesis, angular momentum, L = mvr is quantized as integer multiples of (h-bar): L = n(h-bar). Show that if this is true, orbital radius is also quantized: r = n^2aB.
aB = (hbar)^2/(ke^2m(electron))

First: This isn't the right place to post your homework questions.
Second: You're not following the rules on homework questions either.

sorry this is my first time on, where do I go for help on HW and the rules
