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 :
($\epsilon_0$=8.85 × 10-12 C2N-1m-2)
(1) 5.00 C2N-1m-2
(2) 0.44 × 10-13 C2N-1m-2
(3) 1.77 × 10-12 C2N-1m-2
(4) 0.44 × 10-10 C2N-1m-2
