65. An electromagnetic circuit composed of a capacitor and a planar coil. The distance between the capacitor plates d = 2,0 mm, S = area of the plates of 200 cm2. Solenoid length l = 7,0 cm, the number of turns N = 800, the cross-sectional area S1 = 1,5 cm2. To determine the frequency ω0 own oscillation circuit.
