The function of a dielectric in a capacitor is

The graph shows the variation of voltage (v) across the plates of two parallel plate capacitors $A$ and $B$ versus increase of charge $Q$ stored in them. Then

In between the plates of parallel plate capacitor of plate separation '$d$' a dielectric plate of thickness '$t$' is inserted. The capacitance becomes one-third of the original capacity without dielectric. The dielectric constant of the plate is

An air filled parallel plate capacitor has a capacity \(2\ \text{pF}\). The separation of the plates is doubled and the interspace between the plates is filled with dielectric material, then the capacity is increased to \(6\ \text{pF}\). The dielectric constant of the material is

A parallel plate air capacitor is charged upto $100\ \text{V}$. A plate $2\ \text{mm}$ thick is inserted between the plates. Then to maintain the same potential difference, the distance between the plates is increased by $1.6\ \text{mm}$. The dielectric constant of the thick plate is

A parallel plate capacitor filled with oil of a dielectric constant 3 between the plates has capacitance 'C'. If the oil is removed, then the capacitance of the capacitor will be

In between the plates of parallel plate capacitor of plate separation '$d$' a dielectric plate of thickness '$t$' is inserted. The capacitance becomes one-third of the original capacity without dielectric. The dielectric constant of the plate is
