when cotton is rubbed with a nylon cloth, it gives electrons to the nylon. What is the charge of the nylon cloth after this?
What is a negative charge?
300
Balloons are made of rubber. When the rubber is rubbed with wool, it takes negative charges from the balloon, which stick on the balloon and don't move. Is rubber a insulator or conductor?
Insulator

Before a balloon is rubbed with wool, what type of charge does it most likely have?
Nuetral
400
Two ways to increase electric force.
What is decreasing distance or increasing charge?
400
What happens to the amount of force between charges if the distance is decreased?
Force in stronger

If a object has 2,000 protons, how many electrons will it need to be neutral?
What is 2,000?
500
A negatively charged object is brought near the left side of a metal sphere. A grounding wire is attached to the right side of the metal sphere. This wire takes the extra negative charges away. Later, the negatively charged object and the grounding wire are removed. This is the charge left on the metal sphere.
What is a positive charge?
500
The metal leaves of a electroscope are pushing away from one another. What is the name for this and why does it happen.
This is repulsion and it happens because they have the same charge.
500
Two balloons hanging by a string taped to the ceiling are pushing away from one another. What is the cause of this.
What is the repulsion of like charges?
500
Why is distance a bigger factor to determine the force than the amount of charge involved?
Distance is squared in the formula!!!
