Exam-style question
Try this first
In a particle interaction, the total charge before the interaction is +2. If one of the particles produced has a charge of -1, what must be the charge of the other particle produced?.
Model answer
What a good answer should say
- +3
Explanation
Why this works
This question tests the understanding of charge conservation in particle interactions. The total charge must remain constant before and after the interaction, hence if one particle has a charge of -1, the other must have a charge of +3 to maintain the total charge of +2.
