A hanging iron wire with diameter 1.9 mm (1.9 × 10-3 m) is initially 0.75 m long. When a 68 kg mass is hung from it, the wire stretches an amount 0.881 mm. A mole of iron has a mass of 56 grams, and its density is 7.87 g/cm3. Find the approximate value of the effective spring stiffness of the interatomic bond. N/m
