What happens when two different neutral bodies are rubbed against each other?

1. They acquire equal and opposite charges.
2. They acquire equal and identical charges.
3. They do not acquire any charge.
4. They acquire opposite charges but in different amounts depending upon their masses.

The correct option is A They acquire equal and opposite charges.
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer). Therefore, they acquire equal and opposite charges.
