When you rub two objects together, you're essentially transferring electrons from one object to the other. The object that loses electrons becomes positively charged because it now has more protons than electrons.

Here's a breakdown:

* Electrons: Tiny, negatively charged particles that orbit the nucleus of an atom.

* Protons: Positively charged particles located in the nucleus of an atom.

* Neutral Object: An object with an equal number of protons and electrons.

What Happens:

1. Friction: The rubbing action creates friction, which provides the energy needed to dislodge electrons from their atoms.

2. Electron Transfer: Some of these loose electrons are transferred from one object to the other.

3. Positive Charge: The object that lost electrons now has more protons than electrons, making it positively charged.

Example:

If you rub a balloon against your hair, electrons from your hair are transferred to the balloon. This leaves your hair with a net positive charge and the balloon with a net negative charge. This is why your hair stands on end after rubbing a balloon against it – the positively charged hair strands repel each other.

In summary: The object that loses electrons becomes positively charged. This happens because it now has more protons than electrons, resulting in an imbalance in charge.
