A capacitor C₁ with capacitance 24 μF is initially charged by connecting it to a source of potential

Question

A capacitor C₁ with capacitance 24 μF is initially charged by connecting it to a source of potential difference Vₒ = 120 V. The source of potential difference is then disconnected. When capacitor C₁ is connected in parallel with another capacitor C₂ with capacitance 12 μF, what is the final energy of the system?
