1
Electric charges of the same sign 1)attract each other. 2)repel each other. 3)exert no forces on each other.

2
Law of Conservation of Charge The amount of charge in any closed system is always constant.

3
True or False: Charge can never be created or destroyed.

4
Electron-positron annihilation http://hyperphysics.phy-astr.gsu.edu/hbase/particles/imgpar/annih.gif Positron(Electron) charge: (-)e = (-)1.6022 x 10 -19 Coulombs

5
Conductors and Insulators With rare exception, a material is either a conductor or an insulator. A conductor has some mobile charges that can flow easily. In an insulator, little or no charge can flow.

6
A charged rod is brought near (but does not touch) a neutral conducting sphere. 1)The sphere is attracted towards the rod. 2)The sphere is repelled from the rod. 3)The sphere doesn’t move. 4)The answer depends on the charge of the rod.

8
If you bring a positively charged insulator near two uncharged metallic spheres that are in contact and then separate the spheres, the sphere on the right will have 1)no net charge. 2)a positive charge. 3)a negative charge.

9
A charged rod is brought near (but does not touch) a neutral insulating sphere. 1)The sphere is attracted towards the rod. 2)The sphere is repelled from the rod. 3)The sphere doesn’t move. 4)The answer depends on the charge of the rod.

Induced atomic dipole
