Calculation of the Capacitance of the Capacitor in the Circuit

To find the capacitance of the capacitor in the given circuit, we need to use the formula for the resonant frequency of an LC circuit:

f = 1 / (2π√(LC))

Where: - f is the resonant frequency of the circuit, - L is the inductance of the coil, - C is the capacitance of the capacitor.

From the given information, we know that the circuit is tuned to a wavelength of 300 meters and the inductance of the coil is 300 mH.

Let's substitute these values into the formula and solve for C:

f = 1 / (2π√(LC))

300,000,000 Hz = 1 / (2π√((300 mH)(C)))

Simplifying the equation, we can square both sides:

(300,000,000 Hz)^2 = 1 / (4π^2(300 mH)(C))

Now, we can solve for C:

C = 1 / (4π^2(300 mH)(300,000,000 Hz)^2)

Using a calculator, we can evaluate this expression to find the value of C.
