Energy Stored in a Capacitor

Two capacitors with capacitance values $C_1=\left(2000\pm 10\right) \mathrm{pF}$ and $C_2=\left(3000\pm 15\right) \mathrm{pF}$ are connected in series. The voltage applied across this combination is $V=\left(5.00\pm 0.02\right) \mathrm{V}$. The percentage error in the calculation of the energy stored in this combination of capacitors is __________.
