Question: According to Bohr’s theory, the angular momentum of an electron in 5th orbit is

Options:

A) 10h/π

B) 2.5h/π

C) 25h/π

D) 1.0h/π

Show Answer

Answer:

Correct Answer: B

Solution:

  • Angular momentum of en electron in nth orbit is given by mvr=nh2π For n= 5, we have Angular momentum of electron =5h2π=2.5hπ
