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:

0.44 x 10 -10 C 2 N -1 m -2

5.00C 2 N -1 m -2

0.44 x 10 -13 C 2 N -1 m -2

1.77 x 10 -12 C 2 N -1 m -2

Text Solution

Verified by Experts

The correct answer is:

Now for parallel plate capacitor,

C = KC 0

= 5 x 8.85 x 10 -12

= 0.44 x 10 -10 C 2 N -1 m -2
