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
