Question
A parallel plate capacitor has plates of area 0.05 m² separated by 0.001 m with air between them. What is its capacitance? (ε₀ = 8.85 × 10⁻¹² F/m)
Correct Answer
Option A is the correct answer.
Detailed Explanation
C = ε₀A/d = (8.85 × 10⁻¹²)(0.05)/(0.001) = 4.425 × 10⁻¹⁰ F = 442.5 pF.
Hint
Multiply ε₀ × area, then divide by separation.
