NEET Physics Magnetic Properties of Materials MCQ Question
If the volume of a cubic domain is 10^-18 m^3 and it contains 8.65 × 10^10 atoms, what is the maximum possible dipole moment if each atomic moment is 9.27 × 10^-24 A m^2?
8.0 × 10^-13 A m^2
9.0 × 10^-13 A m^2
7.5 × 10^-13 A m^2
8.5 × 10^-13 A m^2
Correct Answer
Detailed Explanation
The maximum possible dipole moment is calculated as the product of the number of atoms and the atomic moment, i.e., (8.65 × 10^10) × (9.27 × 10^-24) = 8.0 × 10^-13 A m^2.
