Exam-style question
Try this first
In a particle interaction, a proton (charge +1) collides with a neutron (charge 0). What is the total charge before and after the interaction?.
Model answer
What a good answer should say
- The total charge before the interaction is +1 (from the proton) and after the interaction, it remains +1 since the neutron has no charge.
Explanation
Why this works
This question tests the understanding of charge conservation in particle interactions. The answer is strong because it clearly identifies the charges of the particles involved and confirms that the total charge remains unchanged, demonstrating the principle of conservation of charge.
