How charge can be formed
  • 1 answers

Meghna Thapar 5 years, 10 months ago

​​​​​​When we rub the plastic comb with our dry hair, the plastic comb gets electric charge due to friction. The electrically charged comb then exerts an electric force on tiny pieces of paper and attracts them.

If we take a used ballpen refill and rub it vigorously with a piece of polythene. Then bring it close to small pieces of paper. It attracts pieces of paper. 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.

Thus, an object having electric charge on it is called a charged object.

An object having no electric charge on it is called an uncharged object.
