Question: Two capacitors have the same plate separation, but one has square plates and the other has circular plates. The square plates are a length L on each side, and the diameter of the circular plate is L. The capacitors have the same capacitance because they contain different dielectric materials. The dielectric constant of the material between the square plates has a value of ksquare = 2.1.
Part A: What is the dielectric constant kcircular of the material between the circular plates?
Please show your all work and steps I am really confused.
