MCQ
What is the total charge on the parallel plate capacitor shown?
- A$2Q$
- B$\frac{\text{Q}}{2}$
- ✓$0$
- D$\frac{-\text{Q}}{2}$
✓
Answer
Correct option: C.
$0$
Since the total charge on a capacitor is given by sum of the charges on the two parallel plates, here charge on each plate is equal and opposite, hence $–Q + Q = 0.$ Therefore, the total charge on the capacitor is $0.$
