A useful model of a water molecule is sketched in the figure below, with point charges of 5.2 10-20 C at the H sites and a point charge -10.4 x 10-20 C at the O site. The H-O bond length is 9.6 10-11 m, and the bond angle is theta = 104°.
The diagram is simply Oxygen with two H with theta angle drawn between Hydrogens.
a. What is the total electric potential energy of this model of a water molecule?
b. How much work would be required to completely disassociate the molecule?
