when we rub glass rod with silk cloth.why the charge is transfered only from cloth to rod

Expert Answer:

When a glass rod is rubbed with silk, the electrons from the glass rod are transferred to the silk. This is because in glass, electrons are less tightly bound than in silk. Thus due to loss of electrons, the glass rod gets positively charged, while due to gain of same number of electrons, the silk gets an equal amount of negative charge.
