What are the two types of electric charge?

Define the principle of conservation of charge.
What happens to charge during rubbing materials together?
What is the total charge of a system containing +3 C and -3 C?
Think about how charges interact.
True or False: Charge can be created or destroyed.
Remember the experiments with static electricity.
Two spheres, one with +4 μC and the other with -2 μC, are 1 meter apart. Calculate the net electric force each exerts on the other.
Be careful of the signs of the charges!
An object is charged to +10 μC, and 5 μC of charge is added to it. What is the final charge?
Just sum the two charges together.
