Question
A parallel plate capacitor has a capacitance C. The area of the plate is doubled and the distance between the plates is halved. What is the new capacitance?
Correct Answer
Option D is the correct answer.
Detailed Explanation
C = ε₀A/d. Doubling A (×2) and halving d (×2) results in a factor of 4
Hint
Both changes work to increase the capacitance.
