please help answer this question and figure out the solution for a-d

The values for the components of the circuit shown in the figure are V = 10 V, C = 3.0 uF, and L = 150 mH. When the capacitor is fully charged, you simultaneously open switch S, and close switch S2. S1 V O 52 L 0800 a) Find the frequency of the resulting oscillations, in hertz. b) What is the maximum charge on the capacitor, in coulombs, during the oscillations? c) Find the maximum current through the inductor, in amperes, during the oscillations. d) What is the electromagnetic energy of the oscillating circuit, in joules
