Question

what is meant by charging by friction

Answer 1

Hey, mate here is your answer✌✌》》

Charging by friction involves rubbing two different materials together that have different pulls towards electrons, so that one material will pull away electrons when the materials are separated and both will become charged. A common example of charging by friction is rubbing a balloon against hair.

When a material with a strong pull towards electrons (relatively), like rubber in a balloon, is rubbed against hair, it takes some of the hair's electrons. When the two are separated, the balloon is negatively charged due to the excess electrons, while the hair is positively charged. Moving the balloon close to the hair makes the hair stand up because the opposite charged objects are attracted.

Answer 2

we have seen that when a plastic comb is rubbed with dry hair it acquires charge and attract small piece of paper. the, choir this charge due to rubbing by friction similarly when we rub and ebonite rod with for it also acquire charge so when an object is rubbed against another object there is a transfer of charge from one object to another this transfer of charge is caused by due to friction
