What is the reason for two uncharged bodies to get charged on rubbing?

Two uncharged bodies on rubbing get charged because of friction.


One of the rubbed material loses electrons and becomes positively charged, and the other material gains that electron and becomes negatively charged.

  • When two neutral objects come into contact in a dry environment, electrons can be lost from one object and picked up by the other.
  • When two objects are rubbed together in a dry environment, some items have lost electrons and become positively charged, while others have gained electrons and become negatively charged.
