Answer:
Charge on each metal sphere will be [tex]8\times 10^{8}C[/tex]
Explanation:
We have given number of electron added to metal sphere A [tex]n=10^{12}electron[/tex]
As both the spheres are connected by rod so half -half electron will be distributed on both the spheres.
So electron on both the spheres [tex]=\frac{10^{12}}{2}=5\times 10^{11}electron[/tex]
We know that charge on each electron [tex]e=1.6\times 10^{-19}C[/tex]
So charge on both the spheres will be equal to [tex]q=1.6\times 10^{-19}\times 5\times 10^{11}=8\times 10^{8}C[/tex]
So charge on each metal sphere will be equal to [tex]8\times 10^{8}C[/tex]
