The space between plates of a parallel plate capacitor is filled by a dielectric and it is charged and then battery is removed. Now dielectric slab is slowly drawn out of the capacitor parallel to the plates. The variatiton of the potential of capacitor with respect to the length of the dielectric plate drawn out is

Space between the plates of a parallel plate capacitor is filled with a dielectric slab. The capacitor is charged and then the supply is disconnected to it. If the slab is now taken out then

Between the plates of a parallel plate capacitor a dielectric plate in introduced just to fill the complete space between the plates. The capacitor is charged and later disconnected from the battery. The dielectric plate is then slowly drawn out of the capacitor plates. the plot of the potential difference across the plates and the length of the dielectric plate drawn out is

The space between parallel plates of a parallel plate capacitor C is filled with a oil of dielectric constant k = 2. If the oil is removed, then what will be the capacitance of the capacitor—
