Exam-style question
Try this first
A parallel plate capacitor has a capacitance of 5 µF and is connected to a potential difference of 12 V. Calculate the charge stored in the capacitor. Scenario focus: inverse-square reasoning in a distinct A-Level Physics fields context; identify the field quantity, source, direction, and unit before selecting the answer.
Model answer
What a good answer should say
- The charge stored in the capacitor is 60 µC.
Explanation
Why this works
The correct answer is The charge stored in the capacitor is 60 µC.. This is correct for Capacitance because the stem is testing inverse-square reasoning; the chosen option keeps the field quantity, source interaction, direction, and unit consistent.
The alternatives are weaker because they mix gravitational, electric, magnetic, orbital, or transformer ideas, or they attach the right number to the wrong physical meaning.
