A hanging iron wire with diameter 0.05 cm is initially 1.8 m long. When a 60 kg mass is hung from it, the wire stretches an amount 2.55 cm. A mole of iron has a mass of 56 g, and its density is 7.87 g/cm^{3}.

(a) What is the length of an interatomic bond in iron (diameter of one atom)?

(b) what is the approximate value of the effective spring stiffness of one interatomic bond in iron?
