The capacitance of a parallel plate capacitor with air as medium is 6 F. With the introduction of a dielectric medium, the capacitance becomes 30 F. The permittivity of the medium is : (80 = 8.85 x 10-2 C N- m) (1) 5.00 C2 N-1 m-2 (2) 0.44 x 10-13 C N- m (3) 1.77 x 10-12 C N-1 m2 (4) 0.44 x 10-10 C N- m-2
