Please post each question individually.
A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization.

A parallel-plate capacitor has a plate area of 100c * m ^ 2 and a plate separation of 2.0 cm. has been charged up to 3000 V by a battery. Now, (i) after disconnecting the battery, (ii) keeping the battery connected, the distance between the plates is increased to 5.0 cm intensity of electric field between the plates and the energy of the capacitor. ( epsilon_{0} = 8.85 * 10 ^ - 12 * F * m ^ - 1
