The figure below shows a parallel plate capacitor with a surface area A and with a gap between its plates. A potential difference is applied between them. Then the battery is disconnected and a dielectric sheet of thickness b and with dielectric constant is placed between the plates as indicated. A.- What is the initial capacitance? B.- What free charge appears on the plates? C.- What is the electric field between the plates and inside the dielectric? D) What is the potential difference between the plates when the dielectric is introduced? E) What is the new capacitance when the dielectric is introduced?
