Question

Explain with example, how an object can be charged by friction​

Answer 1

Charging by friction

When insulating materials rub against each other, they may become electrically charged. Electrons, which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.☺

Answer 2

Explanation:

• By rubbing two uncharged objects together, electrons can be transferred from one to the other it is called friction.

• Insulating materials can get electrically charged when they rub against each other. Negatively charged electrons can be 'rubbed off' one material and onto the other. Negatively charged is the material that obtains electrons.

• Glass rubbed with silk and hard rubber rubbed with fur are two examples of materials that can develop a considerable charge when rubbed together.
