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:
Answer: (A) $\dfrac ab$
Connected conductors reach the same potential:
$$\frac{kq_1}{a} = \frac{kq_2}{b} \;\Rightarrow\; \frac{q_1}{q_2} = \frac ab$$
