Answer:
The correct option is;
Sphere I is positively charged and sphere II is negatively charged
Explanation:
The charging of the spheres by induction is achieved by introducing a charge to the metal spheres that are insulated from the ground to prevent loss of charge by placing them on insulating stand
The two spheres are brought into contact by the connection of a conducting wire between the spheres I and II
The presence of the positively charged sphere III draws attracts electrons towards sphere II while the net positive charge moves towards sphere I
While the spheres I and II are still polarized, the conducting wire is removed while the presence of sphere III continues to keep sphere II negative compared to sphere I
After removing the connecting wire, sphere III is removed leaving the excess negative charge on sphere II and the excess positive charge on sphere I
The net charges then evenly redistribute themselves on each sphere creating two oppositely charged spheres.
