Homework Statement

Can anyone figure out how Bohr's angular momentum formula nh/2pie is derived? I can't figure it out. I know it has something to do with angular momentum= which is mvr, and Kinetic energy which is mv^2/2. lol, I am stumped.

Homework Equations

angular momentum= which is mvr, and Kinetic energy which is mv^2/2. l

Welcome to Physics Forums.

Can anyone figure out how Bohr's angular momentum formula nh/2pie is derived?

Angular momentum =nh/2π is postulated, not derived, in the Bohr model.

A fair question would be, what was Bohr's motivation for postulating the quantization of angular momentum? That I do not know.

Thanks a lot. That helped a lot. It will take me a while to truly understand the intuition behind the formula. From what I understand, some of Bohr's Postulates do not follow quantum mechanics. I'm still kind of sketchy with the formula, but thanks for your help, it was a big hint.
