Question
If a parallel plate capacitor of plate area 2m² and plate separation 1m stores a charge of 1.77×10⁻¹¹C, what is the voltage across the capacitor?
Correct Answer
Option A is the correct answer.
Detailed Explanation
C = ε0A/d = 8.85×10⁻¹²×2/1 ≈ 1.77×10⁻¹¹F, and V = Q/C = 1.77×10⁻¹¹/1.77×10⁻¹¹ = 1V.
Hint
Compute C from the plate geometry first, then use V = Q/C.
