B
C
4 U
D
2 U
Text Solution
Verified by ExpertsThe correct answer is:
B
Let q be the charge on each capacitor.
Energy stored, 
Now, when battery is disconnected and another capacitor of same capacity is connected in parallel to the first capacitor, then voltage across each capacitor, 
q/2C
Energy stored
