Ratio of Capacitors

The capacitance of a parallel plate capacitor is given by $C = \frac{\varepsilon A}{d}$. Given two capacitors:

1) Left capacitor: Dielectric constant $2\varepsilon$, area $4A$, distance $d$, labeled $C_1$.

2) Right capacitor: Dielectric constant $\varepsilon$, area $3A$, distance $2d$, labeled $C_2$.

Find the ratio: $\frac{C_1}{C_2} = ?$

This question includes visual content: The image shows two parallel plate capacitor diagrams drawn on grid paper. The left capacitor (labeled C1 below) has dielectric constant 2ε, plate area 4A, and separation distance d. The right capacitor (labeled C2 below) has dielectric constant ε, plate area 3A, and separation distance 2d. The question asks to find the ratio C1/C2.
