Question

A charged balloon attracts or repels a charged refill ?

Answer 1

Actually, when a balloon is rubbed with a woollen cloth, it acquires a negative charge and when a ballpen refill is rubbed with polythene, it gets a positive charge. So, in this case, the negatively charged balloon attracts a positively charged ballpen refill. ... In other words, two negative charges repel each others
