STANDARD Physics Bohr's Model MCQ Question
Type: MCQ-conceptual-Medium
According to Bohr's theory, the angular momentum of an electron in 5th orbit is
A
10h/π
B
25h/π
C
1.5h/π
D
2.5h/π
Correct Answer
Option D
Detailed Explanation
According to Bohr's model, angular momentum (mvr) is quantized and given by nh/2π. For the 5th orbit, n = 5, so angular momentum = 5h/2π = 2.5h/π.
