A capacitor has air as dielectric medium and two conducting plates of area \(12 cm ^2\) and they are \(0.6 cm\) apart. When a slab of dielectric having area \(12 cm ^2\) and \(0.6 cm\) thickness is inserted between the plates, one of the conducting plates has to be moved by \(0.2 cm\) to keep the capacitance same as in previous case. The dielectric constant of the slab is : (Given \(\epsilon_0=8.834 \times 10^{-12} F / m\) )
