In the LC circuit shown in the figure initial current through the inductor is zero, initial voltage across the capacitor is 100 V. Switch S is closed at t = 0 sec. The current through the circuit is
1
7.07 sin (7.07 × 103 t)
2
0.707 cos (7.07 × 103 t)
3
0.707 sin (7.07 × 103 t)
4
7.07 cos (7.07 × 103 t)
