Two wire of some material have length 1: 3 when equal force are applied upon it their extension will be?
Correct answer: A. 1 : 3
- A. 1 : 3
- B. 1 : 9
- C. 9 : 1
- D. 3 : 1
Explanation
The extension of a wire under an applied force is directly proportional to its length when the material and force are constant. Given that the wires have lengths in the ratio 1:3, their extensions will also follow this ratio, resulting in an extension ratio of 1:3. Options B, C, and D are incorrect as they suggest disproportionate extensions that do not align with the principles of material physics.

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.
