Vedclass · Answer

(C) The flow of charge between two conductors connected by a wire depends on their electric potentials,not their total charge. Charge flows from a higher potential to a lower potential.The potential $V$ of a spherical conductor is given by $V = \frac{kQ}{R}$.For the first sphere $(R_1 = 1 \, cm = 0.01 \, m)$:$Q_1 = 1.5 	imes 10^{-8} \, C$$V_1 = \frac{k 	imes 1.5 	imes 10^{-8}}{0.01} = k 	imes 1.5 	imes 10^{-6} \, V$For the second sphere $(R_2 = 2 \, cm = 0.02 \, m)$:$Q_2 = 0.3 	imes 10^{-7} = 3 	imes 10^{-8} \, C$$V_2 = \frac{k 	imes 3 	imes 10^{-8}}{0.02} = k 	imes 1.5 	imes 10^{-6} \, V$Since $V_1 = V_2$,there is no potential difference between the two spheres. Therefore,no charge will flow between them.

Two spheres of radii $1 \, cm$ and $2 \, cm$ are charged with $1.5 \times 10^{-8} \, C$ and $0.3 \times 10^{-7} \, C$ of positive charge,respectively. When they are connected by a wire,the charge will flow:
