1.)Why can a grounded conductor not become polarized? 2.) so how does Gauß help, it only tolls me that there is no e field. 3.) so you are basically saying: Maybe yes, Maybe no?

If I have a grounded conducting material, then I know that $\phi=0$ inside this material, no matter what the electric configuration in the surrounding will be. Now I have a conducting material that is not grounded, then there will be (as long as I am dealing with static problems) no electric...

I am struggling with a derivation that calculates the cross sections for Mie scattering and since the incident light is considered to be a x-polarized plane wave I thought that we would have[ tex ] I_i = \frac{1}{2} \sqrt{\frac{\epsilon}{\mu}} \vert E_0 \vert^2 [ /tex ] , but I do not understand...

well, i thought that maybe the constant dipole moment has an effect on the polarizability and therefore on the possibility to have induced dipole moments.

where exactly? i only see this name when it comes to dielectric spheres, not dipoles?

Hi does anybody here know whether there already exists a theory that describe Mie scattering for spheres that have a constant dipole moment?

Hi I am currently looking for the wavefunction of the bonding orbital of the hydrogen molecule. Does anybody here know how this one might look like? So, since there is no complete analytical solution for the Hydrogen atom Schrödinger equation, I am currently looking for approximations of this...

I think everybody here knows the equation that gives the potential of a point like dipole, but how does the field look like if you have e.g. a metal sphere with radius $R$ and a certain dipol moment, how does this potential look like?

Can somebody explain to me, when equations 2.48 and 2.50 are applicable and what ##\Phi_s## and ##\Phi## actually are? The thing is, I want to find a general equations that determines the field produced by conducting spherical sphere in an external field and was wondering whether these are the...

I am interested in the main difference between transitions from electric fields from Conductive to Conductive/ Dielectric to Dielectric and Dielectric/Conductive media. What are the boundary conditions that an Electric field and a potential has to fulfill? I think I only know it for dielectric...

well, then I am curious whether you could give me an idea, what one would have to solve numerically? for instance in this example. could you just give me an idea about the necessary equations? maybe just choose a similar example that you find comfortable to explain. I would appreciate that very...

Hi Does anybody know how to find out the potential energy of two equally heavy, equally big and equally charged particles that are placed at the boundary layer of two different media(for example such that mercury is at the bottom and oil is on the top of both spheres( if you know the answer...

I am calculating the dipole moment of a metal sphere in a uniform electric field E_0 in z-direction. From here I know that the charge density [look at page 15][1] [URL="[PLAIN]http://www.phy.iitb.ac.in/~dkg/PH-102/conductors.pdf"]http://www.phy.iitb.ac.in/~dkg/PH-102/conductors.pdf[/PLAIN]...

So basically this field does nothing to our sphere or can you think of some effect that will happen due to this field?

if I have a not necessarily homogenous electric field of a charge distribution in an electrolyte and i want to find out what the electric field at some position in the electrolyte is. is there any equation that i could use to consider also electric screening by the ions, so that I will get a...
