Gravity, Electromagnetism, Strong Force, Weak force
3
Q

A
Gravitons
4
Q
What are the exchange particles for the strong force?
A
Gluons/Pions
5
Q
What are the 3 exchange particles for the weak force?
A
w+, w-, z0 bosons
6
Q
What is the exchange particle for electromagnetic force?
A
Virtual Photon
7
Q
Describe how the strong force acts.
A
It is attractive from 0.5fm to 3fm
It is repulsive from 0fm to 0.5fm
It becomes negligible from 3fm onwards
This forces acts within the nucleus to overcome electromagnetic repulsion between protons.
8
Q
Why do unstable nuclei decay?
A
