Worked Solution & Example Answer:The diagram represents a particle interaction - AQA - A-Level Physics - Question 11 - 2021 - Paper 1
Step 1
Which row identifies particles E, F and G?
Answer
To identify the particles E, F, and G based on the interaction depicted in the diagram, we analyze the emission of a beta-plus particle (eta^+). This indicates a transformation of a proton into a neutron, which is associated with the emission of a positron. In this scenario:
- Particle E is typically a quark involved in the interaction, most likely the up quark.
- Particle F would then be the down quark, which is converting due to the b+ decay.
- Particle G is a neutrino, which is emitted to conserve lepton number.
Therefore, the correct identification corresponding to the row in the table is A: up quark, down quark, neutrino.
