52. An electromagnetic circuit composed of the inductance coil L = 0,30 mH and the flat capacitor plate area S = 150 cm2 and the distance between the plates d = 2,0 mm. Determine the permittivity ε of the medium that fills the space between the plates of the capacitor when the circuit is set to the wavelength λ = 630 m.
