2 A parallel plate capacitor having plate area 400 cm and separation between the plates 1 0 mm is connected to a power supply of 100 V A dielectric slab of thickness 0 5 mm and dielectric constant 5 0 is inserted into the gap a Find the increase in electrostatic energy b If the power supply is now disconnected and the dielectric slab is taken out find the further increase in energy c Why does the energy increase in inserting the slab as well as in taking it out
