physics problem

Question 3 (1 point) In an oscillating LC circuit, the total stored energy is (6.3760x10^-1) J and the maximum charge on the capacitor is (3.96x10^-5) C. When the charge on the capacitor has decay to (2.8840x10^-6) C, what is the energy stored in the inductor? Express your result in mJ with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible.
