Two charged conducting spheres of radii aa and bb are connected to each other by a conducting wire. The ratio of charges of the two spheres respectively is:

Options

  1. Aab v\frac{a}{b}~v
  2. Bab\sqrt{a b}
  3. Cba\frac{b}{a}
  4. Daba b

Correct answer

A. ab v\frac{a}{b}~v

Step-by-step solution

Potential at surface will be same Kq1a=Kq2 bq1q2=ab\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}
