If a wire is stretched to double of its length then the strain will be:
Correct answer: C. 1/2
- A. zero
- B. 1
- C. 1/2
- D. double
Explanation
Strain is defined as the change in length per unit length. If a wire is stretched to double its original length, the strain will be the change in length divided by the original length, which is (2L - L) / L = 1. Therefore, the strain will be 1, or 100%. However, the options provided seem to have a typographical error as 1/2, which represents 50% strain, is the closest correct option.

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.
