NEET Physics (general) MCQ Question
Which of the following statements about the modulus of elasticity in solids is correct?
Steel requires a larger force to produce a smaller change in length compared to aluminum.
Materials with higher Young's modulus exhibit greater plastic deformation under stress.
A lower modulus of elasticity indicates a material's ability to withstand high stress without deforming.
The modulus of elasticity is the same for all materials regardless of their composition or structure.
Correct Answer
Detailed Explanation
Steel requires a larger force to produce a smaller change in length compared to aluminum, indicating that steel is more elastic. This is supported by the information that different materials require varying forces for the same strain, with steel needing the most.
