Capacitor 2 has half the capacitance and twice the potential difference as capacitor 1.
What is the ratio Uc1/Uc2.
Where would I start with this problem and what equation would I use?

Uc = 0.5 * C * V^2
C = Capacitance
V = Potential
Then,
C1 = 2C2
V2 = 2V1
Then (Uc)1/(Uc)2
= (0.5 * C1 * V1^2) / (0.5 * C2 * V2^2)
= 2/4 = 0.5
