(D) The capacitance of a parallel plate capacitor with air is given by $C_{0} = 6\, \mu F$.When a dielectric medium is introduced,the new capacitance is $C_{m} = 30\, \mu F$.The dielectric constant $\epsilon_{r}$ is defined as the ratio of the capacitance with the medium to the capacitance with air:$\epsilon_{r} = \frac{C_{m}}{C_{0}} = \frac{30}{6} = 5$.The permittivity of the medium $\epsilon$ is given by $\epsilon = \epsilon_{0} \cdot \epsilon_{r}$.Substituting the given values:$\epsilon = 8.85 \times 10^{-12} \times 5 = 44.25 \times 10^{-12} = 0.4425 \times 10^{-10} \approx 0.44 \times 10^{-10} C^{2} N^{-1} m^{-2}$.

View Solution

$A$ parallel plate capacitor with air between the plates has a capacitance of $1.0 \text{ pF}$. If the distance between the plates is doubled and the space between them is filled with a dielectric substance,the capacitance becomes $2.0 \text{ pF}$. Then the value of the dielectric constant of the dielectric substance is . . . . . . .
