According to Bohrs theory of hydrogen atom angular momentum of electron in any orbit is directly proportional to square root of the radius of orbit. HOW?

Hello Student

Angular momentum = mvr
v=root(ZKe^2/mr)
So Angular Momentum = mvr=root(ZKe^2*r*m)
and that how its proportional to square root of the radius

We know that r=n^2/Z. ............(1)For Hydrogen, Z=1SoEquation (1) became r=n^2orn=√r. ..................(2)We also know thatAngular momentum =nh/2π. ......(3)From eq. (2)We can writeAngular momentum is directly proportional to √r
