If Young's modulus of iron is $2 \times 10^{11} \mathrm{~N} / \mathrm{m}^{2}$ and the interatomic spacing between two molecules is $3 \times 10^{-10} \mathrm{~m}$, the interatomic force constant is (A) $60 \mathrm{~N} / \mathrm{m}$ (B) $120 \mathrm{~N} / \mathrm{m}$ (C) $3 \mathrm{~N} / \mathrm{m}$ (D) $180 \mathrm{~N} / \mathrm{m}$
The Young's modulus of a material is 2x10^10 N/m^2. If its length is doubled, then find the force applied on it if it has an area of 100 m².
