By what method will a positively charged rod produce a negative charge on a conducting sphere that is placed on an insulating surface?

Question

Quizplus · Accepted Answer

When a positively charged rod is brought near a conducting sphere, it induces the electrons to concentrate on the side closest to the rod, leaving a net positive charge on the opposite side. This is called induction. As the conducting sphere is on an insulating surface, it cannot transfer charge through conduction or convection. Therefore, the only plausible option is induction.
