2. A positively charged rod is used to charge a neutral electroscope by conduction. What is the final charge on the electroscope? A. Positive B. Negative C. Neutral D. It depends on the rod's charge.

The correct answer is A. Positive.<br /><br />When a positively charged rod is used to charge a neutral electroscope by conduction, the positive charge from the rod will transfer to the electroscope. As a result, the electroscope will also become positively charged.
