Question1

A molecule of DNA (deoxyribonucleic acid) is 2.35 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 1.01 percent upon becoming charged. Determine the efficient spring constant of the molecule.

Question2
