Question

The capacitance of a parallel plate capacitor with air as medium is 6 µF. With the introduction of a dielectric medium, the capacitance becomes 30 µF. The permittivity of the medium is : 

(ε₀ = 8.85 × 10^–12 C² N^–1 m^–2) 

(1) 5.00 C² N^–1 m^–2 

(2) 0.44 × 10^–13 C² N^–1 m^–2 

(3) 1.77 × 10^–12 C² N^–1 m^–2 

(4) 0.44 × 10^–10 C² N^–1 m^–2

Answer 1

Correct answer is  (4) 0.44 × 10^–10 C² N^–1 m^–2
