In a parallel plate capacitor, two parallel plates each of area $0.25 \times m^2$ are placed close to each other. A substance of dielectric constant 2.1 is inserted in the separation between the plates. The capacitance of the parallel plate capacitor is $4.65 \times 10^{−10}\; F$. What is the distance between the two plates?
