An ebonite rod is rubbed with fur. Compare the charges acquired by them.

A metal rod A is to be charged positively by using another charged rod B. What should be the kind of charge on the rod B if charging is to be done by conduction?

Figure below shows a metal rod AB placed on an insulating stand. In Fig.(a), a negatively charged ebonite rod C is touched with the metal rod AB, while in Fig.(b), the negatively charged ebonite rod C is held near the rod AB. State the kind of charges at the ends A and B of the rod, in each case.
