The mean distance between the atoms of iron is 3 x 10⁻¹⁰ m and interatomic force constant for iron is 7 N/m. The Young’s modulus of elasticity for iron is
Correct Answer :
2.33 x 10¹⁰ N / m²
Solution :
The correct option is 2.33 x 10¹⁰ N / m².
Step-by-step Explanation:
Young's modulus of elasticity () of a material is related to its interatomic force constant () and the mean interatomic distance () by the formula:
Given data:
Interatomic force constant for iron,
Mean distance between the atoms of iron,
Substitute these values into the formula to find Young's modulus:
Therefore, the Young's modulus of elasticity for iron is .
