Question

If $r$ and $v$ represent, respectively, the orbital radius and orbital velocity of the electron in the Bohr's theory of hydrogen atom, then they are proportional to the orbit number as

• A. $r\propto n,\; v\propto n$
• B. $r\propto n,\; v\propto \dfrac{1}{n^2}$
• C. $r\propto n^2,\; v\propto \dfrac{1}{n}$
• D. $r\propto \dfrac{1}{n},\; v\propto n$
• E. $r\propto n^2,\; v\propto n$

Hint:

Physics Tip: In Bohr atom, outer orbit = larger radius but slower electron.
