Question

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

Answer 1

1. When two uncharged bodies are rubbed together, due to friction they get charged
2. Electrons can be lost from one object and picked up by the other when two neutral objects come into contact in a dry environment.
3. When two dry objects are rubbed together, some lose electrons and become positively charged, while others gain electrons and become negatively charged.
