The angular momentum of electron of ` H-atom is proportional to :

Options

A. `r^(2)`
B. `1/r`
C. `r^(1/2)`
D. `1/(sqrt(r))`

Answer

C

Explanation

Angular momentum `=mvr`
Also from Bohr.s theory `=(e^(2))/(r^(2))=(mv^(2))/r`
`implies(e^(2))/(r^(2))xxmr^(2)=(mv^(2))/rxxmr^(2)`
`implies^(2)v^(2)r^(2)=e^(2)mr`
Hence c is the correct option.
