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 : (∈₀ = 8.85 × 10^–12 C² N^–1 m^–2)

(1) 1.77 × 10^–12 C² N^–1 m^–2

(2) 0.44 × 10^–10 C² N^–1 m^–2

(3) 5.00 C² N^–1 m^–2

(4) 0.44 × 10^–13 C² N^–1 m^–2
