Object a has a positive charge after object a touches object b A still has a positive charge and the same amount of charge what can you infer about the charge of b

We can infer that the charge on object B is Neutrally charged.

Explanation:

From the above we can assume object B is neutral and was charged by induction.

During the process of charging by conduction, both objects A and B acquire the same type of charge after contact.

It follows the rule that says that if a positively charged object A is used to charge a neutral object B, then both objects A & B become charged positively charged.
