Document Summary
This was an excerpt from your textbook; more material can be found on pages 780-802. Sketch the lowest energy (most stable) orientation of the water molecule in this uniform field. E tend to align their dipole moments as shown below (small red arrows). On average, what will be the direction of the electric field created by the water dipoles? (hint: look back at the previous page) Is the total electric field larger or smaller than the original field. Activity 5: electric fields and forces with dielectrics. The polarization of the dielectric means that the total electric field is reduced from what it would have been. We describe this phenomenon using the dielectric constant, : As a general rule of thumb, if you have a dielectric everywhere around an object, you can just replace: Suppose you have two ions with charges q1 and q2 in a dielectric (such as water: = 80).
