A question about LRC Series Circuits

L=1h, C=10f, and electromotive force of E(t)= 100 sin 50t V. Initially the charge q and the current i are zero.
The question: Find the times for which the charge on the capacitor is zero. (Hint: the current i(t)= dq/dt)

Can anyone help me to answer the question?
(or at least help me to get start it)

Thank you VERY much,
Ryan

You are missing some information.

How are the inductor and the capacitorc connected - in series or parallel?

in series, but nevermind.
I got it now.

Thank you.
