The table below shows the resistivity, length, and diameter of two cylindrical wires, X and Y.
| Wire | Resistivity | Length | Diameter |
|---|---|---|---|
| Wire X | ρ\rhoρ | LLL | ddd |
| Wire Y | 2ρ2\rho2ρ | LLL | 2d2d2d |
The resistance of wire X is RRR.
What is the total resistance when these two wires are connected in parallel?
13R\frac{1}{3}R31R
12R\frac{1}{2}R21R
23R\frac{2}{3}R32R
32R\frac{3}{2}R23R
