The plates of parallel plate capacitor are charged upto `100V`. A `2mm` thick dielectric slab is inserted between the plates.Then to maintain the same potential difference,the distance between the plates is increased by `1.6mm`. The dielectric constant of the slab is.

The plates of a parallel plate capacitor are charged to 100V. Then a 4mm thick dielectric slab is inserted between the plates and then to obtain the original potential difference , the distance between the system plates is increased by 2.00 mm. the dielectric constant of the slab is

The plates of a parallel plate capacitor are charged up to 100 v . Now, after removing the battery, a 2 mm thick plate is inserted between the plates Then, to maintain the same potential deffernce, the distance betweem the capacitor plates is increase by 1.6 mm . The dielectric canstant of the plate is .

A parallel plate capacitor is maintained at a certain potentail difference. When a 3mm thick slab is intorduced between the plate, in a order to maintain the same potential difference, the distance between the plates is increased by 2.4 mm. Find the dielectric constant of the slab.

Explain why the capacitance of a parallel plate capacitor increases when a dielectric slab is introduced between the plates.

A dielectric slab is inserted between the plates of an isolatted capacitoe. The forcebetween the plates will

A parallel plate capacitor carries a harge Q. If a dielectric slab with dielectric constant K=2 is dipped between the plates, then

When a dielectric slab of thickness 4 cm is introduced between the plates of parallel plate condenser, it is found the distance between the plates has to be increased by 3 cm to restore to capacity to original value. The dielectric constant of the slab is.

A parallel plate capacitor is charged by a battery. The battery is removed and a thick glass slab is inserted between the plates. Now,
