Dear student,
 
False,
 
What happens when you comb your dry hair and then bring the comb near a few small pieces of paper? Combing your dry hair will move some of the subatomic particles called electrons from hair to the comb. The charge of an electron is negative and thus the comb will also gain the charge of an electron (negative charge). Finally, when the comb is brought near the bits of paper, the bits of paper will get attracted to the comb.
 
Similarly, what happens when you rub a silk cloth on a glass rod and then the glass rod is brought near an inflated balloon? The electrons from the glass rod are transferred to the silk cloth. Hence, the glass rod becomes positively charged. When the positively charged glass rod is brought near the inflated balloon, it will be attracted to the glass rod.
