Electrostatic interaction Definition and 14 Threads

Hi community, I am trying to find an expression of coercive field in lithium niobate crystals on the context of interaction energy, we know that the coercive field in ferroelectrics is the reverse electric field necessary to bring the polarization to zero, in other words and in the case of...

I think it is negative because of the ##g_{\mu \nu}## metric tensor, but I am not sure.

Hello! I want to get the electrostatic interaction (between and electron and a nucleus), while accounting for the fact that the electron can also be inside the nucleus (e.g. in an S##_{1/2}## state). I ended up with this double integral...

How will the repulsion of electrons occur in the simulation hypothesis? The electrons will also create electrostatic fields around yourself ?

Homework Statement this is a theoretical question.please consider the situation as follows: we are charging a metallic sphere using induction phenomenon with the help of a postively charged metallic rod and while on grounding the electrons flow from the ground to the sphere rather than sphere...

Homework Statement Find the interaction energy ( ##\epsilon_0 \int \vec{E_1}\cdot\vec{E_2}d\tau##) for two point charges, ##q_1## and ##q_2##, a distance ##a## apart. [Hint: put ##q_1## at the origin and ##q_2## on the z axis; use spherical coordinates, and do the ##r## integral first.]Homework...

Homework Statement [/B] Thin rod of length l is placed with one of its ends at the center O of the (thin circular )ring of radius R as shown (Figure 1), perpendicular to the plane of the ring. The rod is charged with total charge Q that is distrubted along the rod's length with linear charge...

I understand that every force has an equal and opposite reaction, and the reason things can move is because the forces acts on different things. Also, F=MA is why the heavier object is accelerated less. The equal and opposite reaction to gravity pulling down towards the Earth's core on a book...

Homework Statement Consider the following pair of dipoles in one dimension. One of the dipoles: -ve dipole positioned at (-D/2, 0) and +ve (+D/2, 0), with the origin between them. Other dipole: -ve dipole positioned at (r-d/2, 0) and +ve at (r+d/2, 0), with (r, 0) being the centre. Show that...

How to find electrostatic interaction energy between two uniformly charged conducting spheres /uniformly charged non conducting spheres or between a charge and uniformly charged spherical shell I mean what is general method of finding electrostatic energy in a given system.I don't have any...

Homework Statement Thin rod of the length l is placed with one of its ends placed at the center Oof the thin ring of radius R as shown, perpendicular to the plane of the ring. Rod is charged with total charge Q that is distributed along the rod’s length with the linear charge density...

hello! which equation descripts the electrostatic interaction between two non-point (ie. that have dimensions) charged particles? thanks!

There is given two neutral parallel plates, distance between them is d. Between them is putted insulating plate with a thikness of d. After that one of two plates was charged positively. How can I find electrostatic interaction force?

Homework Statement I am trying to follow a derivation in Jackson - Classical ElectrodynamicsHomework Equations In equation 1.58 (2nd/3rd edition) of Jackson - Classical Electrodynamics he says that by using the fact that \mathbf{\rho} \cdot (\mathbf{\rho} +\mathbf{n})/ | \mathbf{\rho +n|}^{3}...
