Question
A spherical capacitor consists of two concentric spherical conductors, held in position by suitable insulating supports (2.36). Show
that the capacitance of a spherical capacitor is given by $\text{C}=\frac{{4}\pi\in_{0}\text{r}_1\text{r}_2}{\text{r}_1-\text{r}_2}$ where $r_1$ and $r_2$ are the radii of outer and inner spheres, respectively.
