Answer:
new energy of the capacitor is half that of initial energy
Explanation:
As we know that the energy stored in the capacitor is given as
here we know that capacitance of parallel plate capacitor is given as
V = voltage of battery
so now we have capacitor remains connected to the same battery and the separation between the plates is doubled
so we have
so now the energy stored between the plates is
so new energy of the capacitor is half
