STANDARD Physics Bohr's Model MCQ Question
Type: MCQ-conceptual-Medium-Class 11
An electron in the ground state of hydrogen atom is revolving in anticlockwise direction in circular orbit of radius R. The orbital magnetic dipole moment of the electron will be
A
eh/2πm
B
eh²/4πm
C
eh/4πm
D
e²h/4πm²
Correct Answer
Option A
Detailed Explanation
The magnetic dipole moment is given by the formula M = (e/2m) * L, where L is the angular momentum. For an electron in the ground state, L = h/2π. Substituting this value gives M = eh/2πm.
