 Imagine that you have a glass of water in which all of the water molecules are aligned, so that their positive ends all point upwards. Imagine that each molecule can be treated as a simple dipole consisting of two charges (1 and —q separated by a small vertical distance a. In this case, the water is like two superimposed charge densities, one positive and one negative, displaced vertically by a tiny distance a. If the water in a glass is in this aligned state, what is the magnitude of the electric ?eld E in the water? Your answer should depend on the product go, which is the dipole moment of the water molecule, which you can look up (be careful with units!). What would be the potential difference V in volts from the top to the bottom of a pint glass of water in this aligned state? Do you think this ever happens in nature? Clearly state all your assumptions, approximations and estimates.
