When a glass rod is rubbed with silk cloth, then what kind of the electric charge produce on the glass rod


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.
