Two isolated conducting spheres, Sphere 1 of radius \(R\) and Sphere 2 of radius \(2R\), are connected by a long, thin conducting wire. A total net charge \(Q_0\) is placed on the system, and charge redistributes until electrostatic equilibrium is established. Which of the following correctly gives the ratio of the electrostatic potentials at their surfaces, \(V_1 / V_2\), and the ratio of the net charges on the spheres, \(Q_1 / Q_2\)?
