Question

a charged rod is held close to a metal can. the can is on insulated stand. a) what type of induced charge is formed on the can ? b) why is the can attracted to the rod even though the net charge on the can is zero ? c) if you touch the can with your finger , electrons flow through it . In which direction is the flow ? d) what type of charge is left on the can after it has been touched ?​

Answer 1

However, it is not the only process by which objects become charged. In this section of Lesson 2, the charging by induction method will be discussed. Induction charging is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process. If you are not already comfortable with these topics, you might want to familiarize yourself them prior to reading further.
