what happens to polythene,glass and perspex when they are rubbed with silk and woolen in turn?

Question

I want to get an answer with a scientifical explanation regarding static electricity

Answer 1

If a glass rod is rubbed with silk, the glass acquires a positive charge because elecrons move from the glass to the silk. If a plastic rod is rubbed with wool, the plastic acquires a negative charge because elecrons move from the wool to the plastic. Rubbing two dissimilar objects together tends to cause electrons to move from one material to the other; the specific atomic properties of the two substances generally govern which material loses electrons and which one gains.
