Question
The capacitance of a parallel plate capacitor with air as medium is 6$\mu $F. With the introduction of a dielectric medium, the capacitance become 30 $\mu $F The permittivity of the medium is :
$\left( {{\varepsilon _0} = 8.85 \times {{10}^{ - 12}}{C^2}{N^{ - 1}}{m^{ - 2}}} \right)$
$\left( {{\varepsilon _0} = 8.85 \times {{10}^{ - 12}}{C^2}{N^{ - 1}}{m^{ - 2}}} \right)$
