It is also said that glass rod attracts the small uncharged paper pieces when it is becomes positively charged. I understand that a positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod, but can't we extend the same argument on attraction of negatively charged silk rod and the pieces of paper due to accumulation of positive charge near the end

 the important thing to note is that in your typical solid material, the positive charges, which are the cores of the atoms, cannot move around much. They are locked into a rigid structure. The tiny electrons, however, can move around much better. That's why the glass rod can induce a net negative charge at one end of the paper clips.

When we rub glass rod with silk cloth and bring it near an inflated balloon then glass rod will acquire positive charge.

  • Because transfer of electrons takes place from glass rod to silk cloth thereby leaving glass rod positively charged. Due to the deficiency of electrons in the glass atoms, it becomes positively charged.
  • the positive charges cannot move in a rigid structure. The tiny electrons, however, can move around easily. That's why the glass rod can induce a net negative charge on inflated balloon.
