In a circuit shown in Fig. 4.29 the battery emf is equal to ε = 2.0 V, its internal resistance is r = 9.0Ω, the capacitance of the capacitor is C = l0μF, the coil inductance is L = 100 mH, and the resistance is R = 1.0Ω. At a certain moment the switch Sw was disconnected. Find the energy of oscillations in the circuit
(a) Immediately after the switch was disconnected;
(b) t = 0.30 s after the switch was disconnected.
