Q. Interatomic spring constant

you hang a heavy ball with a mass of 13 kg from a copper wire 2.80m long that is 2mm in diameter. You measure the stretch of the wire, and find that the wire stretched 0.000938 m.
analyse Young's modulus for the wire.

The atomic mass of copper is 64 g/mole, and the density of copper is 8.9 g/cm3.
Compute the interatomic spring stiffness for copper.
