A conducting wire connects two charged metallic spheres A and B of radii $\displaystyle \mathrm{r}_{1}$ and $\displaystyle \mathrm{r}_{2}$ respectively. The distance between the spheres is very large compared to their radii. The ratio of electric fields, $\displaystyle \left(\mathrm{E}_{\mathrm{A}} / \mathrm{E}_{\mathrm{B}}\right)$ at the surfaces of spheres A and B will be
Official answer
(B)
$\displaystyle \frac{\mathrm{r}_{2}}{\mathrm{r}_{1}}$
