Two capacitors C₁ = 4 $\mathrm{\mu }$F and C₂ = 2 $\mathrm{\mu }$F are charged to same potential V = 500 Volt, but with opposite polarity as shown in the figure. The switches S₁ and S₂ are closed.

The ratio of final energy to initial energy of the system is 1/9.

The ratio of final energy to initial energy of the system is 4/9.

The potential difference across the two capacitors are same and is given by $\frac{500}{3}\mathrm{V}$

The potential difference across the two capacitors are same and is given by $\frac{1000}{3}\mathrm{V}$
