Two parallel plates have a surface charge density of material is inserted in between the two plates with dielectric constant K. Use Gauss' Law to find the and - respectfully and an area of A. The plates are oriented in the x-z plane, one is located at y=0 and the other is located at y=a. A dielectric electric field in all regions. Find the Capacitance of the system and the potential energy stored in the capacitor.
