The correct Answer is:
To determine the order of materials (Copper, Steel, Glass, and Rubber) based on their coefficients of elasticity, we need to understand the concept of elasticity and how it varies among different materials. ### Step-by-step Solution: 1. **Understanding Coefficient of Elasticity**: The coefficient of elasticity (also known as Young's modulus) measures a material's ability to deform elastically (i.e., non-permanently) when a force is applied. A higher coefficient indicates that the material is stiffer and less prone to deformation. 2. **Identifying the Materials**: - **Rubber**: Known for its flexibility and ability to stretch, rubber has a low coefficient of elasticity. - **Glass**: More rigid than rubber, glass has a higher coefficient of elasticity. - **Copper**: A metal that is more elastic than glass, copper has a moderate coefficient of elasticity. - **Steel**: Known for its strength and rigidity, steel has the highest coefficient of elasticity among the four materials. 3. **Arranging the Materials**: Based on the understanding of their elastic properties, we can arrange the materials in order of increasing coefficient of elasticity: - Rubber (lowest) - Glass - Copper - Steel (highest) 4. **Final Order**: Therefore, the order of the materials from lowest to highest coefficient of elasticity is: - Rubber < Glass < Copper < Steel ### Conclusion: The correct order at increasing coefficient of elasticity is: **Rubber < Glass < Copper < Steel**

The correct order of increasing order of size is

The property of a body by virtue of which it tends to regain its original configuration as soon as the deforming forces applied on the body are removed is called elasticity. Coefficient of elasticity, E = (stress)/("strain") = (F//a)/(Delta l//l) = (F l)/(pi r^2(Delta l)) The value of E depends upon nature of material. A material with higher value of E is said to be more elastic. Read the above passage and answer the following question : (i) Which is more elastic steel or rubber ? Why ?
