Two conducting spheres $S1$ and $S2$ of radii $a$ and $b$ ($b>a$) respectively, are placed far apart and connected by a long, thin conducting wire, as shown in the figure.
For some charge placed on this structure, the potential and surface electric field on $S1$ are $V_a$ and $E_a$ and that on S2 are $V_b$ and $E_b$, respectively. Then, which of the following is CORRECT?
- $V_a=V_b$ and $E_a<E_b$
- $V_a>V_b$ and $E_a>E_b$
- $V_a=V_b$ and $E_a>E_b$
- $V_a>V_b$ and $E_a=E_b$
