(D) The potential of a charged sphere of radius $r$ with charge $q$ is given by $V = \frac{kq}{r}$.Since both spheres have the same charge $q$,their potentials are $V_P = \frac{kq}{r_1}$ and $V_Q = \frac{kq}{r_2}$.Given $r_1 > r_2$,it follows that $V_P If the charge $q$ is positive,the potential $V_Q$ is higher than $V_P$,so positive charge flows from $Q$ to $P$.If the charge $q$ is negative,the potential $V_P$ is higher (less negative) than $V_Q$,so negative charge flows from $P$ to $Q$.Since the nature of the charge (positive or negative) is not specified,the direction of flow cannot be determined uniquely. Thus,the information is incomplete.

The radii of two metallic spheres $P$ and $Q$ are $r_1$ and $r_2$ respectively. They are given the same charge. If $r_1 > r_2$,then on connecting them with a thin wire,the charge will flow
