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 :
(``e_0 =8.85 \times 10^{-12} C^2 N^{-1} m^{-2} ``)
(1) 0.44×``10^{-13} C^2 N^{-1} m^{-2}``
(2) ``1.77×10^{-12} C^2 N^{-1} m^{-2}``
(3)`` 0.44 × 10^{-10} C^2 N^{-1} m^{-2}``
(4) ``5.00 C^2 N^{-1} m^{-2}``
