It is required to calculate the change in the energy stored in a capacitor when the capacitor remains connected to a battery and  the separation of the plates is doubled.

Step-by-step explanation

Step 1.
The energy stored in a capacitor calculated as,
 
Where C= the capacitance
V= potential difference
 
The capacitance C is calculated as,
 
Where d= the separation between plates
A= area of the plate
