Question

Quizplus · Accepted Answer

When the negatively charged rod is brought near the can, it induces a positive charge on the side of the can closest to the rod and a negative charge on the opposite side. Touching the can allows electrons to flow from the can to the ground through your body, leaving the can with a net positive charge.
