When a dielectric is inserted in the space between parallel plates of a charged capacitor, then

When dielectric is inserted in the space between plates of a capacitor, then

The strength of electric filed in the charged and isolated capacitor is decreased when the dielectric slab is inserted. When the dielectric slab is inserted between the plates of a charged capacitor, electricfield produced due to induced charged, opposite to the external field.

When a thick plate of a dielectric is place in the air space of a parallel plate capacitor, then

When a dielectric is introduced between the plates of a charged parallel plate capacitor, whichi one of the following will not change?

The capacity of a parallel plate capacitor with air is 18 pF. When a dielectric material is inserted in the space between the plates, its capacity becomes 108 pF. Calculate the permittivity of the material. What is the material?

Statement I: A dielectric slab is inserted between the plates of an isolated charged capacitor. The charge on the capacitor will remain the same. Statement II: Charge on an isolated system is conserved.
