Negative strain indicates that
Correct answer: B. Length is decreased
- A. Length is increased
- B. Length is decreased
- C. Length remains same
- D. None of these
Explanation
Strain is defined as the ratio of change in length to the original length.Strain = (Change in length)/ (Original length)If the change in length is negative, it means the length has decreased

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.
