The capacitance of a parallel -plate capacitor is C_(0) when the region between the plates has air. This region is now filled with a dielectric slab of dielectric constant K . The capacitor is connected to a cell of emf varepsilon and the slab is takenout

The space between the rectangular plates (with sides a and b ) of a parallel-plato capacitor (the distance between the plates is l) is filled with a solid dielectric whose dielectric constant is c. The capacitor is charged to a certain potential difference and disconnected from the voltage source. After that the dielectric is slowly moved out of the capacitor, which lTIOanS that the section x not filled with the dielectric gradually increases in size. How wi ll the potential difference between the plates and the surface charge densities on both parts of the capacitor (with and without the dielectric) change in the process?
