A molecule of DNA (deoxyribonucleic acid) is 2.22 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 0.95% upon becoming charged. Determine the effective spring constant of the molecule.
q= charge on one elctron, d is given k coulombs constant, x=.0095*d
solve for k
