An LC circuit constructed of a 1 microF capacitor and a 1 microH inductor
is set in oscillation so that the charge on the capacitor is 1.0 microC at t = 0
and 2.0 microC at t = 1.57 x 10^-6 s. What is the charge on the capacitor at
t = 1.0 s?
Q(t) = Q0cos(wt), w = angular frequency = 1 / sqrt(LC), L = inductance
The Attempt at a Solution
At first glance, it seemed like a simple plugin problem using t = 1.0 s and Q0 = 1.0 microC in the equation..
but i'm not sure why the problem tells me the charge at t = 1.57 x 10^-6 s
is this just extra unrelated information? or is my method incorrect?
