A radio can tune over the frequency range of a portion of MW broadcast band: (800 kHz to 1200 kHz). If its LC circuit has an effective inductance of `200 muH`, what must be the range of its variable capacitor?

The medium wave(MW) band coresponds to wavelength range 200 m to 625 m.If a radio can tune to any station in this and,what is the corresponding frequency band?

An inductor of inductance 2.0 mH s connected across a charged capacitor of capacitance 5.0 mu F and the resulting LC circuit is set oscillating at its natural frequency. Let Q denote the instantaneous charge on the capacitor and I the current in the circuit. It is found that the maximum value of charge Q is 200 mu C. When I is equal to one-half its maximum value, what is the value of Q?
