I have been learning gauss's law in capacitor recently, recently I come up with this problem that I couldn't solve myself. If we have a capacitor,and a dielectric medium with half the volume between the plates, the permittivity of the dielectric is epsilon.Find the electric field inside the dielectric. The second one is when the dielectric only covers half the area. First picture (Symbols are E1,E2,Epsilon for clarification) Again,What is the Electric field in the dielectric?Express In terms of Q A(area) epsilon0 and epsilon . How do we go about solving this problem?Is there anything to do with boundary conditions?
