Charged Objects
Physics: Edexcel IGCSE, topic 2.5.3
Charged Objects
Charged objects can exert forces on other objects.
Rubbing an object
- Rubbing an object against another object can cause electrons to jump from one object to the other. This causes both objects to become charged.
Charged rod
- A plastic rod (or a balloon) can be charged by rubbing it with a cloth (or hair).
- The charged rod will attract a gentle stream of water falling from a tap.
- The charged rod can move an empty aluminium drink can. The charge on the rod attracts or repels the electrons in the metal, moving the can.
