Two capacitors C_(1)"and"C_(2) are charged to the same potential V, but with opposite polarity as shown in the figure. The switch S_(1)"and"S_(2) are then closed.

Answer»

PDsacross. Two capacitors are the same and is GIVEN by `((C_(1)-C_(2))V)/((C_(1)+C_(2))`
PDsacross two capacitors are the same and is given by `(C_(1)V)/((C_(1)+C_(2))`
Ratio of final energy to initial energy of the SYSTEM is `(((C_(1)-C_(2)))/((C_(1)+C_(2))))^(2)`
Ratio of final energy to initial energy of the system is `(((C_(1)))/((C_(1)+C_(2))^(2)))`

Answer :`(A,C)`
