1. The problem statement, all variables and given/known data A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.0 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.50 H . What is the charge on the capacitor after a time interval of 2.30×10−2 s after the connection to the inductor is made? 2. Relevant equations q(t)=Qcos(ωt+∅) 3. The attempt at a solution I have answered a couple questions prior to this question. I found these: ω = 106 rad/s Period of the electrical oscillations T = 5.94*10^-2 s Initial charge of the cap Q = 7.14*10^-4 C Energy initially stored in the cap 4.28*10^-3 J For the question where i had to find the charge, I used q(t)=Qcos(ωt+∅) and got 7.13*10^-4 which is wrong. I plugged 2.30*10^-2 for time t and the ∅=0.
