Question

two objects rubbed against each other acquire charges. a) what is the relationship between the charges acquired by the two objects?b) what action does rubbing cause, because of which the objects acquire charge?

Answer 1

when an ebonite rod is rubbed with fur the ebonite rod gets negatively charged when a glass rod is rubbed with Silk the glass rod gets positively charged A positively charged body loses electrons and negatively charged body gain electrons what is with like or similar charges repel each other on the other hand bodies with unlike charges attract each other when an ebonite rod is rubbed with fur electrons are transferred from the for to the ebonite rod therefore due to deficiency of electrons the for Bcom positively charged and the axis of electron makes the ebonite rod negatively charged similarly exchange of electrons takes place between a glass rod and double glass rod losses electron and become positively charged and double gets negatively charged on scanning electron so it is proved that body sweet like or similar charges repel each other on the other hand bodies with unlike charges attract each other.
