Задача 31501.

The period of sustained oscillations in the resonant circuit is equal to 10 ^ -3 s. The peak value of current equal to 0.40 A, the coil inductance 0.05 Gn. Determine the capacitance of the capacitor. Write a law changing the voltage on the capacitor plates over time. Determine the energy of the electric field at the time when the current equals half the maximal value. Loop resistance neglected.

Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
