please answer

Activity: If a SOD-V dc power supply Is used to charge a 25-pF capacitor. After the capacitor is fully charged. It is disconnected from the power supply and connected saves a 20-mH Inducton The resistance in the circuit is negligible. (a) Find the frequency and period oi oscillation of the circuit 03) Find the capacitor charge and the circuit current 1.6 ms after the inductor and capacitor are connected. Then nd for the magnetic and electric energies (c) at and (d) at i - 1.6 ms
