How will you give equal and opposite charge to two identical metal spheres on insulated stands ? You can use a charged rod but touching of rod to spheres is not allowed

How can we charge two metallic spheres with equal and opposite charge using the method of induction?

Figure shows that a positively charged rod is brought near two ucharged metal spheres A and B clamped on insulated stands and palced in contact with each other. (i) What would happen if the rod is removed before the spheres are separated? (ii) Would the induced charges be equal in magnitude even if the spheres had different sizes or different conductors? (iii) What will happen if the spheres are separated first and then the rod is removed far away?
