Two charged conducting spheres of radii $a$ and $b$ are connected to each other by a conducting wire. The ratio of charges of the two spheres respectively is:
$\frac{a}{b}~v$
$\sqrt{a b}$
$\frac{b}{a}$
$a b$
Solution
Potential at surface will be same
$\begin{aligned} & \frac{\mathrm{Kq}_1}{\mathrm{a}}=\frac{\mathrm{Kq}_2}{\mathrm{~b}} \\ & \frac{\mathrm{q}_1}{\mathrm{q}_2}=\frac{\mathrm{a}}{\mathrm{b}}\end{aligned}$
