Task 40174.
The oscillating circuit includes a coil with an inductance of 5 mH and a flat capacitor with a glass dielectric. The distance between the capacitor plates is 6 mm, the plate area is 90 cm ^ 2. How much will the frequency and period of oscillation of the circuit change if the glass layer of the capacitor is noticeable to be air? ε1 = 7; ε2 = 1.
A detailed solution with a short recording of the conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the solution, write. I try to help.
