Decide the effective spring constant of the molecule

Reference no: EM13672071

A molecule of DNA (deoxyribonucleic acid) is 2.24 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 1.34% upon becoming charged. Decide the effective spring constant of the molecule.
