The capacitance of a parallel plate capacitor with air as medium is \( 6\ \mu\text{F} \). With the introduction of a dielectric medium, the capacitance becomes \( 30\ \mu\text{F} \). The permittivity of the medium is: (\( \varepsilon_0 = 8.85 \times 10^{-12}\text{ C}^2\text{N}^{-1}\text{m}^{-2} \))

   \( 1.77 \times 10^{-12}\text{ C}^2\text{N}^{-1}\text{m}^{-2} \)
2. B
   \( 0.44 \times 10^{-10}\text{ C}^2\text{N}^{-1}\text{m}^{-2} \)
3. C
   \( 5.00\text{ C}^2\text{N}^{-1}\text{m}^{-2} \)
4. D
   \( 0.44 \times 10^{-13}\text{ C}^2\text{N}^{-1}\text{m}^{-2} \)
