In the following electrical network at \( t0 \) (figure),
P key is placed on (1) till the capacitor got fully

W charged. Key is placed on (2) at \( t=0 \). Time when the energy in both the capacitor and the inductor will be same for the first time is
(1) \( \frac{\pi}{4} \sqrt{L C} \)
(2) \( \frac{3 \pi}{4} \sqrt{L C} \)
(3) \( \frac{\pi}{3} \sqrt{L C} \)
(4) \( \frac{2 \pi}{3} \sqrt{L C} \)
