A parallel plate capacitor consists of two metallic plates separated by a small distance with a dielectric in between : A parallel plate air capacitor has charge densities + sigma and - sigma on the plates. Write the expres sion for electric field between the plates. What happens to the field if the separation between the plates is doubled?
