\( \mathrm{N} \) identical capacitors are joined in parallel and the
\( \mathrm{P} \)
combination is charged to a potential V. Now if the
W
are separated and then joined in series then energy of combination will :-
(1) remain same and potential difference will remain same
(2) remain same and potential difference will become NV
(3) increase \( \mathrm{N} \) time and potential difference will become NV
(4) increase \( \mathrm{N} \) time and potential difference will remains same
