Bold your choices (all that apply) What kinds of interactions are possible between these pairs of particles? For each pair, is there a net attraction or repulsion? What virtual particles do they exchange? Proton - proton (closer than 10-15m) Interactions gravitation electromagnetic miclear/strong Net interaction attraction repulsion Exchange Particles gravitons O photons gluons Proton - electron Interactions gravitation electromagnetism nuclear Net interaction attraction repulsion Exchange Particles gravitons photons gluons Neutron- neutron (closer than 10-15m) Interactions O gravitation electromagnetism nuclear Net interaction attraction repulsion Exchange Particles O gravitons photons gluons Neutron-electron Interactions O gravitation electromagnetism nuclear Net interaction attraction repulsion Exchange Particles gravitons photons gluons
