Hello In DNA, thymine and adenine molecules are attracted to each other. The solid lines show bonds between atoms in the same molecule and the dotted line shows bonds between atoms in different molecules. Atoms in the same molecule are seperated by 1e-10 m. If the net charge on the H and N atoms is 0.2e and the net charge on the O atom is 0.4e, what is the force between the H and O atoms in different molecules? my workings: charge for H atom = 0.2 X (1.6e-19) = 3.2e-20 C charge for O atom = 0.4 X (1.6e-19) = 6.4e-20 C k = 9e9 Nm^2/C^2 I need to work out the distance between the O and H before i can work out the force. Can someone point me in the right direction?
