Exam-style question
Try this first
Which of the following interactions would violate conservation laws?.
- A.A reaction where total charge is conserved
- B.A decay where baryon number decreases
- C.An interaction where energy is conserved
- D.A collision where momentum is conserved
Model answer
What a good answer should say
- A decay where baryon number decreases
Explanation
Why this works
In particle interactions, the baryon number must remain constant. A decay that results in a decrease of baryon number violates this conservation law.
