Figure E21.22 shows the bonding of cytosine and guanine. The O—H and H—N distances are each 0.110 nm. In this case, assume that the bonding is due only to the forces along the O—H—O, N—H—N, and O—H—N combinations, and assume also that these three combinations are parallel to each other. Calculate thenet force that cytosine exerts on guanine due to the preceding three combinations. Is this force attractive or repulsive? Help please. I have been stuck for hours now
