Silk cloths: Negatively charged
Glass rod: Positively charged
When the glass rod is rubbed with silk clothes, glass quickly loses electrons, and silk takes electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge.
- So glass acquires a greater order than silk as electron losses.
- Therefore, on rubbing, glass gets a positive charge and silk gets a negative charge.
- On both of them, equal but opposite charges are produced.
