Question

My Notes Ask Your Tescher You are working in a biology lab during your summer break. Your supervisor asks you to perform an experiment to find the ive spring constant (in N/m) of a partial molecule of DNA (deoxyribonucleic acid). You perform experiments and find that a single straight each end portion of a DNA molecule is 2.30 um long. You then perform an activity that charges the ends of the molecule; becomes singly ionized: negative on one end, positive on the other. After the ends are charged, the molecule shrinks by 1.40% of its length. Use the particle in equilibrium model to balance the electric and elastic forces on a particle at one of the ends of N/m Need Help? Read
