Задача id13527

The oscillating circuit contains inductance and capacitance. At some point, a plate with dielectric constant e = 4 is quickly removed from the capacitor. How will the oscillation frequency of the circuit change? How many times will the maximum values of the charge on the capacitor and the current in the coil change if the plate is removed at the moment when the charge on the capacitor is a) absent and b) maximum?
