The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure (Figure 1) shows the thymine-adenine bond. Each charge shown is te, and the H-N distance is 0.110 nm. Figure < 1 of 1 > ▾ Part A Calculate the net force that thymine exerts on adenine. To keep the calculations fairly simple, yet reasonable, consider only the forces due to the O-H-N and the N-H-N combinations, assuming that these two combinations are parallel to each other. Remember, however, that in the O-H-N set, the O exerts a force on both the H+ and the N, and likewise along the N-H-N set. Express your answer in newtons.
