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 -10.4x10^-20 C at the O site. The H-O bond length is 9.6 10^-11 m, and the bond angle is theta= 104°.
(a) What is the total electric potential energy of this model of a water molecule? (eV)
(b) How much work would be required to completely disassociate the molecule? (eV)
