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=8.85×1012 C2 N1 m2
  1. 1.77×1012 C2 N1 m2
  2. 0.44×1010 C2 N1 m2
  3. 5.00 C2 N1 m2
  4. 0.44×1013 C2 N1 m2

Solution

Cm=rC0

r=306=5

=0.r=8.85×1012×5

=0.44×1010
