A $\displaystyle 60$ pF capacitor is fully charged by a $\displaystyle 20$ V supply. It is then disconnected from the supply and is connected to another uncharged $\displaystyle 60$ pF capacitor in parallel. The electrostatic energy that is lost in this process by the time the charge is redistributed between them is (in nJ)
