4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
lyudmila [28]

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
