Electrostatic Potential and Capacitance

The capacitance of a parallel plate capacitor with air as medium is $6 μ F$ . With the introduction of a dielectric medium, the capacitance becomes $30 μ F$ . The permittivity of the medium is: ( $ε_{0} = 8.85 \times 1 0^{- 12} C^{2} N^{- 1} m^{- 2}$ )

A. $0.44 \times 1 0^{- 13} C^{2} N^{- 1} m^{- 2}$
B. $1.77 \times 1 0^{- 12} C^{2} N^{- 1} m^{- 2}$
C. $0.44 \times 1 0^{- 10} C^{2} N^{- 1} m^{- 2}$ ✓
D. $5.00 C^{2} N^{- 1} m^{- 2}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
