Question

The picture shows three sets of balloons, all with a particular charge. Which of the picture(s) is true? Please explain.

Then please explain why the other two pictures are incorrect.

Please make sure to explain all three sets.

Answer 1

Letter C has the correct illustration. Two objects with the same charge (in this case, both are positively charged) will repel each other.

Letter A is incorrect because a positive charged object will attract a negatively charged object.

Letter B is incorrect because both of them are negatively charged, which means they should be repelling each other.
