Topic 5 - Energy

If you have two objects have a charge and they push away from each other no matter how close you put them together, what hypothesis can be true?

• The first object is a positive charge and the second charge is a negative charge.

• Both charge have a negative charge and pull towards each other.

• The first object has a negative charge and the second object has a positive charge, so the objects push away.

• Both objects have the same charge and push away from each other.
