The lowest frequency in the FM radio band is 88.2 MHz.
(a) What inductance (in µH) is needed to produce this resonant frequency if it is connected to a 2.65 pF capacitor?
(b) The capacitor is variable, to allow the resonant frequency to be adjusted to as high as 108 MHz. What must the capacitance be (in pF) at this frequency?
