A molecule of DNA (deoxyribonucleic acid) is m 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 upon becoming charged, and remains in this equilibrium position. Determine the effective spring constant of the molecule.
