The current strength in an oscillatory circuit, consisting of a coil with an inductance of 2.0 H and a capacitor connected in series, changes with time according to the law I \u003d 5 * 10 ^ -3 * sin2 * 10 ^ 3t, A. Determine the capacitance of the circuit, the oscillation period in the circuit, the energy of electric and magnetic fields at time t1 = T/2. Ignore the loop resistance.
