A charged capacitor is connected to an ideal inductor. At time t = 0, the charge on the capacitor is equal to 6.00 C.

At time t = 2.00 ms the charge on the capacitor is zero for the first time. What is the amplitude of the current at that same instant?
A) 0.780 mA B) 1.19 mA C) 2.38 mA D) 4.71 mA E) 1.53 mA
