Electron Collision: Proton & Electron Interaction

AI Thread Summary
When a negatively charged electron interacts with a positive proton, they do not annihilate like an electron and positron; instead, they can merge to form a neutron under certain conditions. This process occurs during events such as the collapse of a star into a neutron star. In radioactive nuclei, a proton can absorb an atomic electron, emit a neutrino, and transform into a neutron, a phenomenon known as electron capture or K-capture. This interaction highlights the complex behavior of subatomic particles and their transformations. Understanding these processes is crucial for comprehending stellar evolution and nuclear physics.

What happens when a negatively charged electron interacts with a positive proton, do they annihilate like electron and positron and produce photons? (i know they can't collide in an atom but if they were fired from opposite sides).

Electrons and protons can merge into neutrons. That's what happens when a star collapses into a neutron star.
 
Hi xmonty-
Sometimes a proton in a radioactive nucleus can absorb an atomic electron, emit a neutrino, and become a neutron. This is called electron capture or K-capture. See

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...
