question 23

Multiple Choice

When the potential difference between the plates of an ideal air-filled parallel plate capacitor is 35 V, the electric field between the plates has a strength of 750 V/m. If the plate area is 4.0 × 10^-2 m², what is the capacitance of this capacitor? (ε₀ = 8.85 × 10^-12 C²/N ∙ m²)

• A) 7.6 × \(10^{ - 14}\) F
• B) 7.6 × \(10 ^{- 12}\) F
• C) 7.6 × \(10^{ - 11}\) F
• D) 7.6 × \(10 ^{- 10}\) F
• E) None of the other choices is correct.
