Step-by-step walkthrough of a WebAssign.net homework problem pertaining to the spring constant of DNA as ascertained by a tandem application of Hooke's Law and Coulomb's Law.

From WebAssign:

"A molecule of DNA (deoxyribonucleic acid) is 2.33 µm long. The ends of the molecule become singly ionized: negative on one end, positive on the other. The helical molecule acts like a spring and compresses 1.00% upon becoming charged, and remains in this equilibrium position. Determine the effective spring constant of the molecule."
