Atomic Structure Question 405
Question: According to Bohr’s theory, the angular momentum of an electron in 5th orbit is
Options:
A) $ 10h/\pi $
B) $ 2.5h/\pi $
C) $ 25h/\pi $
D) $ 1.0h/\pi $
Show Answer
Answer:
Correct Answer: B
Solution:
- Angular momentum of en electron in $ n^{th} $ orbit is given by $ mvr=\frac{nh}{2\pi } $ For n= 5, we have Angular momentum of electron $ =\frac{5h}{2\pi }=\frac{2.5h}{\pi } $
