Which statement explains what will happen to the negative charge, and why?

Answer 1

The negative charge will transfer from the rod to the metal sphere because oppositely charged objects attract each other. When the negatively charged rod is touched to the neutral metal sphere, the negative charges will move from the rod to the sphere until both objects have the same charge. This is known as charge transfer by conduction.
