Question

According to Bohr's theory of hydrogen atom, for an electron in the $n^{th}$ allowed orbit, then

• A. linear momentum is proportional to $\left(1/n\right)$
• B. radius is proportional to $n$
• C. the kinetic energy is proportional to $\left(1/n^2\right)$
• D. the angular momentum is proportional to $n$

Answer 1

Answer: (A), (C), (D)

The correct options are
A linear momentum is proportional to $\left(1/n\right)$
C the kinetic energy is proportional to $\left(1/n^2\right)$
D the angular momentum is proportional to $n$

Linear momentum is inversely proportional to $n$ and angular momentum is directly proportional to $n$.

We have the equation,

$E=-13.6\frac{z^2}{n^2}$

So, $K.E.\alpha \frac{1}{n^2}$
