Try this first
In a particle interaction, a proton (charge +1) decays into a neutron (charge 0) and a positron (charge +1). What is the charge of the missing particle in this interaction?.
Model answer
What a good answer should say
- The missing particle must have a charge of -1 to conserve charge.
Explanation
Why this works
This question tests the understanding of charge conservation in particle interactions. The total charge before and after the interaction must be equal, hence the missing particle's charge is calculated to ensure this balance.
