When a dielectric material is introduced between the plates of a charged condenser the electric field between the plates

When a dielectric material is introduced between the plates of a charged condenser, after disconnected the battery the electric field between the plates

An uncharged parallel plate capacitor is connected to a battery. The electric field between the plates is 10V/m. Now a dielectric of dielectric constant 2 is inserted between the plates filling the entries space. The electric field between the plates now is
