On the surface of the sphere $A$

(B) When two metallic spheres are connected by a thin wire,charge flows until their electric potentials become equal.Let the charges on spheres $A$ and $B$ be ${Q_1}$ and ${Q_2}$ respectively.The potential $V$ of a spherical conductor is given by $V = \frac{kQ}{r}$.Since the potentials are equal,we have $\frac{k{Q_1}}{{r_1}} = \frac{k{Q_2}}{{r_2}}$.This simplifies to $\frac{{Q_1}}{{Q_2}} = \frac{{r_1}}{{r_2}}$.Given that ${r_1} > {r_2}$,it follows that ${Q_1} > {Q_2}$.Therefore,the charge on the surface of sphere $A$ will be greater.
