Can't identify the 4 fundamental interactionsWatch
An example of the kind of question I'm on about is like this:
Two particles (proton and neutron) transform in to an electron anti-neutrino and an electron (through a W- boson), state the type of interaction that occurs in this decay.
Can anyone please explain to me the best way possible to identify the different interactions?
Apparently I can't read Feynman diagrams either, what I meant to say was the neutron turns into the proton through emitting a W- which decays into an electron and electron-antineutrino.
The best way to identify them is to pretty much learn them, there aren't even many to learn. Electron capture, electron-proton collision, Beta-Plus and Beta-minus are all examples of the weak interaction taking place. Electromagnetic repulsion is an example of the electromagnetic interaction. Only hadrons can interact via the strong interaction so if you have a question only involving hadrons, the interaction will most definitely be the strong interaction.
