# Very Annoying Problem

• LuGoBi
In summary, the conversation discusses calculating the electric field generated by a charge on the bottom of a container filled with water, taking into account the differences between the electrostatic constants in air and water. The method of images is mentioned as a way to solve this problem, but the speaker suggests consulting a textbook for more information. There is also a mention of using Gauss' Law and trigonometry as other potential approaches.

This is killing me. I have an electrical charge in the air and below it I have a container filled with water. How do I calculate the electric field generated by the charge on the bottom of the cointainer? Bear in mind the electrostatic constant in water is different than from air.

Assuming the surface of the water is like an infinite plane, this is a standard image problem treated in most textbooks.

Could you ellaborate, then?

I can't go through the whole method of images.
You may have to look at a book.

smells like homework?

Excuses me, pam (or others), but doesn't the method of images require that the boundary region be a (grounded) perfect conductor?

Treating the problem in a brute-force manner (Gauss' Law, Cartesian coordinates), this doesn't sound TOO bad. You just need to invoke some pretty clever trigonometry to account for the surface of the water.
