At time t = 0, terminal A in the circuit shown in the figure is connected to B by a key and an alternating current I(t) = I

_{0}cos ($$\omega$$t), with I_{0}= 1 A and $$\omega$$ = 500 rad s^{-1}starts flowing in it with the initial direction shown in the figure. At $$t = {{7\pi } \over {6\omega }}$$, the key is switched from B to D. Now onwards only A and D are connected. A total charge Q flows from the battery to charge the capacitor fully. If C = 20 $$\mu$$F, R = 10 $$\Omega$$ and the battery is ideal with emf of 50 V, identify the correct statement(s).2
