Question
In the Bohr's model of the hydrogen atom, let $r, v$ and $E$ represent the orbit radius, speed of an electron and the total energy of the electron, respectively. Which of following relation is proportional to the orbit number $n$?
Answer: A
💡 Solution & Explanation
We know $v \propto \frac{1}{n}$ and $r \propto n^2$. Their product $v \cdot r \propto \frac{1}{n} \cdot n^2 = n$. Therefore, correct answer is A.
