1. Who’s right?
2. Super Mario is right!
Like charges repel
and opposite charges attract
But why do they act like that?
3. Every electric charge acts with a repulsive electric force (push) on another charge of like sign,
while the same charge acts with an attractive electric force (pull) on another charge of opposite sign.
The branch of Physics that studies these charges and their forces is called ELECTROSTATICS.
4. Electrostatics When a polythene rod is rubbed by a duster, electrons are scratched away from the duster and stay on the rod
5. Electrostatics In the same way, when an acetate rod is rubbed, electrons are scratched away and stay on the duster
6. Having fun with electrostatics Now, rub a duster on your polythene (or acetate) rod and place the rod near the following objects:
Small chips of paper
A thin line of running water from the tap
Then, record what happened in your book and try other things you can do with your rod or an air balloon and add them to your list.
