The diagram represents a particle interaction - AQA - A-Level Physics - Question 11 - 2021 - Paper 1

To identify particles E, F, and G based on the given particle interaction diagram, we need to consider the nature of the particles involved in the interaction depicted.

In the diagram, particle E is typically a fermion, and given the interactions usually involve quarks and leptons, we can analyze the options:

• Particle E is likely a quark, specifically an up quark or a down quark.
• Particle F, being on the opposite side, could represent another quark or possibly a boson depending on the interaction type.
• Particle G is likely a neutrino due to its non-charged nature.

After evaluating the options:

• Option A: E is up quark, F is down quark, G is neutrino. This makes sense given the electron-neutrino interaction in beta decay scenarios commonly represented in particle physics.
• Other options suggest different configurations but don't fit the particle nature as well as option A.

Thus, the correct identification for E, F, and G based on the particle interaction is:

• E: up quark
• F: down quark
• G: neutrino
