Question

Why does a plastic refill acquire a small electric charge when rubbed with polythene ???

Answer 1

When a plastic refill is rubbed with polythene, it acquires a small electric charge. Similarly, when a plastic comb is rubbed with dry hair, it acquires a small charge. These objects are called charged objects.

Answer 2

Explanation:

When a plastic refill is rubbed with polythene, both plastic refill and polythene acquire an electric charge. Like charges repel each other and unlike charges attract each other. When a glass rod is rubbed with a silk cloth, glass acquires a positive charge and silk cloth acquires a negative charge.
