Insertion Of Dielectric Between Plates

On inserting a dielectric between the plates of a capacitor, its capacitance is found to increase 5 times. What is the relative permittivity of the dielectric?

A dielectric is inserted between the plates of an isolated fully-charged capacitor. The dielectric completely fills the space between the plates. The magnitude of electrostatic force on either metal plate decreases, as it was before the insertion of dielectric medium. Due to insertion of dielectric slab in an isolated parallel plate capacitor (the dielectric completely fills the space between the plates), the electrostatic potential energy of the capacitor decreases.

A parallel plate capacitor is connected to a battery and inserted a dielectric plate between the place of plates then which quantity increase

Two capacitors are connected in parallel to a battery. If a dielectric medium is inserted between the plates of one of the capacitors then the enegry stored in the system will increase. On inserting dielectric medium between the plates of a capacitors, its capacity increases.

A parallel plate capacitor (without dielectric) is charged by a battery and kept connected to the battery. A dielectric salb of dielectric constant 'k' is inserted between the plates fully occupying the space between the plates. The energy density of electric field between the plates will:

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

By inserting a plate of dielectric material between the plates of a parallel plate capacitor at constant potential, the energy is increased five times. The dielectric constant of the material is
