Find the velocity (ms^(-1)) of electron ...

Find the velocity `(ms^(-1))` of electron in First Bohr's orbit of radius `a_(0)`. Also find the de Broglie's wavelength (in m). Find the orbital angular momentum of 2p obrital of hydrogen atom in units of `h/(2pi)`.
`3.34xx10^(-10)msqrt(2)h/(2pi)`
a. `mvr=(nh)/(2pi)r=a_(0)=0.529Å` b. `lamda=h/(mv)=(6.63xx10^(-34))/(9.1xx10^(-31)xx2.18xx10^(8))=0.33xx10^(-9)m=3.3Å`
c. For 2 p value of `l=1`
Orbital angular momentum `=sqrt(l(l+1))h/(2pi)=sqrt(2)h/(2pi)`
