Calculate the electrostatic energy of this configuration, which is therefore the magnitude of the energy released in forming this molecule. (Note: Your answer is an overestimate because electrons are actually "shared" among the three atoms, spending more time near the oxygen.) 105 2.

Find a) the electric field between the plates, b) the potential difference between the plates, and el the stored energy
