Question: A molecule of DNA (deoxyribonucleic acid) is 2.07 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 1.25% upon becoming charged, and remains in this equilibrium position.
Part A: Determine the effective spring constant of the molecule.
____ N/m
I want help to find the effective spring constant of the molecule.
