A DNA molecule (deoxyribonucleic acid) is 2.17µm long. The ends of the molecule become singly ionized so that there is -1.60x10^-19 C on one end and +1.60x10^-19 C on the other. The helical molecule acts as a spring and compresses 1.00 percent upon becoming charged. Find the effective spring constant of the molecule.
