Answer
becomes positively charged while the cloth has a negative charge.
Reason — When two objects are rubbed against each other, electrons transfer from one material to the other. This transfer of electrons leads to one material becoming positively charged (losing electrons) and the other becoming negatively charged (gaining electrons). It is a convention to call the charge acquired by a glass rod when it is rubbed with silk as positive. The other kind of charge is said to be negative.
