Find what the effective spring constant of the molecule

Reference no: EM13699243

Problem: A molecule of DNA (deoxyribonucleic acid) is 2.33 Âµm 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 0.81% upon becoming charged.

Part A: Determine the effective spring constant of the molecule.
