I am really confused about the behaviour of electric field through dielectrics.
I have a question:
Let's suppose that I have two point charges, and , separated by free space. Now the force of attraction between them is clearly obtained by coulombs law, ie:
Now suppose that instead of free space, the whole system is in a dielectric, then again we clearly conclude to:
where is the dielectric constant of the dielectric in which the system is contained.
Now suppose that the separation between the two point charges is partially free space and partially the dielectric s.t. none of the charges is contained in the dielectric, then:
I am a bit doubtful about this relation. As this would imply that a metal sheet would completely prevent the two particles from interacting with each other which is not the case.
I feel that there is a grave error in my concepts.
Please help me on this.
Thanks and regards: Prabhpreet
