Question

why electrons are transferred from glass rod to Silk clothes​

Answer 1

When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge. ... The tiny electrons, however, can move around much better.

Answer 2

Its due of friction of electrostatic force. Since only eletrons can move freely then proton or neutron so they move from lower potential to higher potential.
