Problem 3.114

A capacitor of capacitance $C_{1}=1.0 \mu \mathrm{F}$ withstands the maximum voltage $V_{1}=6.0 \mathrm{kV}$ while a capacitor of capacitance $C_{2}=2.0 \mu \mathrm{F},$ the maximum voltage $V_{2}=4.0 \mathrm{kV} .$ What voltage will the system of these two capacitors withstand if they are connected in series?
