An LC circuit with a 3.0 μF capacitor and a 3.0 H inductor has a current I(t) = 10.0sin(2.0t) supplied to it. After 2 s, how much charge is stored on a plate of the capacitor?
Select one:
1. 0.19 C
2. 8.3 C
3. 0.030 C
4. 20 C
Please HELP!!

The voltage across the cap is (1/C)*integral(I(t) dt)=-1.67E6 cos(2 t)=1.09E6 volts at 2 seconds.
Q=C V=3.3 coul
