Question:

Consider the LC circuit in Problem 42 and Figure P22.42. At t = 0, the current is I = 45 mA and the charge q on the capacitor is zero.
(a) What is the energy stored in the inductor at t = 0?
(b) At some instant t₁, the current will be zero. What is the charge on the capacitor at t₁?
(c) Find t₁. (There are many possible values of t₁; find the one closest to t = 0.)
(d) Using the value of t₁ from part (c), find the magnitudes of I and q at t = 3t₁.
