The force constant of a wire does not depend on
Correct answer: D. None of the above
- A. Nature of the material
- B. Radius of the wire
- C. Length of the wire
- D. None of the above
Explanation
The force constant of a wire is influenced by the nature of the material, the radius of the wire, and its length. The material determines the intrinsic elastic properties of the wire. The radius affects the cross-sectional area, which in turn affects the stiffness, while the length influences how much the wire can stretch. Therefore, all these factors play a role in determining the force constant of the wire. The correct answer is 'None of the above' because each option lists a factor that does affect the force constant.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
