can these be combined??
why does the angular momentum,L of a electron in allowed orbit (for instance,n=3) is different when i used L=mrw
and L=nh/2pi??I'hv assumed tat the electron as non-relastivistic..
i let speed of electron =70x105m/s and rn=ao9
*mass of electron,me=9.1x10-31kg
K=1/2mev2-(1)
K=mer2w2-(2)
(1)=(2)
1/2mev2=1/2mer2w2
v=rw
v=rnw where the rnis the radius of permissible orbit in atom
v=ao9x w
w=1.47x1016
then,i started to find L (not 'light"in death note of course ^^)
L=mrw
=m(9ao)w
=6.37x10-24J s
but when i used L=nh/2pi the answer is 3.17x10-34J s
is the angular velocity couldn't use in this respect or the different is negligible??
