A slab of material of dielectric constant K has the same area as the plates of a parallel plate capacitor, but has a thickness 3d//4 . Find the ratio of the capacitanace with dielectric inside it to its capacitance without the dielectric.

A parallel plate capacitor is charged by a battery. After some time the battery is disconnected and a dielectric slab of dielectric constant K is inserted between the plates. How would (i) the capacitance, (ii) the electric field between the plates and (iii) the energy stored in the capacitor, be affected ? Justify your answer.

A capacitor of capacitance C is charged to potential difference V and then disconnected from the battery. The air dielectric of capacitor is replaced by another dielectric of dielectric constant K. The fractional decrease in energy of the capacitor is
