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.

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 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 .

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

A parallel plate capacitor is connected across a source of covstant potential difference. If a dielectric slab is introduced between the two plates, then

A parallel plate capacitor is charged to a certain potential difference. A slab of thickness 3 mm is inserted between the plates and it becomes necessary to increase the distance between the plates by 2.4 mm to maintain the same potential difference. The dielectric constant of the slab is

A parallel-plate capacitor is charged to a certain potential difference. A slab of 3 mm thickness is inserted between the plates, and it becomes necessary to increase the distance between them by 2.3 mm to maintain the same p.d. Find the dielectric coefficient of the slab. [Hint: See examples 3]

The distance between the plates of a parallel plate condenser is 4mm and potential difference is 60 volts. If the distance between the plates is increased to 12mm , 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.

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