1
Q
EM force
A
- Newtons 3rd law, momentum transferred between objects vis force if no external force acts (photons approach, repel)
- EM force between 2 charged object due to exchange of virtual photons (cant be detected directly / intercepted)

A
3
Q

A
- Holds neutrons & protons in nucleus
- Does not cause neutron to change to proton in β- decay
- Does not cause proton to change to neutron in β+ decay
