Two experiments are performed using positively charged glass rods and neutral electroscopes. In the first experiment the rod is brought in contact with the electroscope. In the second experiment the rod is only brought close to the electroscope but not in contact. However, while the rod is close, the electroscope is momentarily grounded and then the rod is removed. In both experiments the needles of the electroscopes deflect, which indicates the presence of charges. a. What is the charging method in each of the two experiments? b. What is the net charge on the electroscope in the first experiment? Explain how the electroscope obtains that charge. c. Is the net charge on the electroscope in the second experiment different from that of the first experiment? Explain why.
