Can you explain the answer of this question below:
Two identical capacitors are joined in parallel, charged to a potential V, separated and then, connected in series, i.e., the positive plate of one is connected to the negative plate of the other. Then:
  • A:
    the charges on the free plates connected togetherare destroyed
  • B:
    charges on the free plates are destroyed
  • C:
    the energy stored in the system increases
  • D:
    the potential difference between the free plates is 2V
The answer is a.

Can you explain the answer of this question below:Two identical capaci...
The charges on two capacitors are equal to 
q1 = q2 = CV, 
where C — capacitance of each capacitor. 
V' - new potential difference between free plates. 
Using charge conservation, 

q1 + q2 = CV + CV = 2CV, 
q'1 + q'2 = CV1 + CV2 = CV', 
q1 + q2 = q'1 + q'2 —> 2CV = CV', V' = 2V. 
Correct answer is D. potential difference between free plates is 2V.
