Two large, parallel conducting plates are separated by a distance of d=2 mmd = 2 \, \text{mm}. Each plate has an area of A=0.02 m2A = 0.02 \, \text{m}^2. The region between the plates is filled with a material with dielectric constant [x]. Find the capacitance (in , one decimal place) of the capacitor.
