Physics-Bohr Model
NEET Physics Bohr Model MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram illustrating the Bohr model of the hydrogen atom, with circular orbits labeled as n=1, n=2, and n=3. Which of the following correctly describes the condition for the angular momentum of an electron in the n=2 orbit?
A
The angular momentum is 2h/2π.
B
The angular momentum is h/mv.
C
The angular momentum is mv/2π.
D
The angular momentum is 2mv/nh.
Correct Answer
Option A
Detailed Explanation
In the Bohr model, the angular momentum of an electron in an orbit is quantized and given by the formula mvr = nh/2π. For n=2, it becomes 2h/2π.
