Question 11 A student is performing an experiment that involves the charge on a metal sphere that is attached to a charged electroscope. A charged rod is brought near the sphere without touching it. As a result the leaves of the electroscope separate more. The rod is then removed, and the leaves return to their initial separated position. The student repeats the procedure, but this time the electroscope is grounded and the ground is removed before the rod is removed from near the sphere. The leaves again end up separated. What can be concluded about the charge on the separated leaves of the electroscope? A B с D The leaves have a positive charge in the first trial and a negative charge in the second trial. The leaves have a negative charge in the first trial and a positive charge in the second trial. The leaves have the same sign charge in the first trial as in the second trial. The leaves have a charge in the first trial opposite to the charge in the second trial, but the sign of the charge for each trial cannot be determined.
