Size Electron: Energy Increase, Size Unchanged?

Electron

AI Thread Summary

Increasing the energy of an electron does not change its size, which remains effectively point-like. The concept of a point-like particle implies that while it has no spatial extent, it can still interact through a potential that behaves like 1/r. This means that the electron can exert influence over a distance, akin to having "infinitely long hands." The idea of energy existing without a physical size raises intriguing questions about the nature of particles and their interactions. Ultimately, the electron's behavior is defined by its energy rather than any change in size.

If the energy of an eletron is increased, is its size also increased? If not, how can it be that something (energy) can have the size of nothing?

The electron has "infinitely long hands" to interact. It is very sticky. When they say it is "point-like", thay mean the interaction potential has a simple form like 1/r where there is a maximum at only one point.

Thread 'Free surface problem in electrohydrodynamics'

I'm thinking about the following problem. I have an electrified fluid with a constant charge density, Q, within the fluid. Will this necessarily yield a surface charge? Would I have to compute it by looking at the displacement fields on either side of the interface? Would it change if the bulk charge within the fluid remains constant?

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
