What is an electric field?
100
The particles that move away from the dome of the Van De Graaff Generator.
What is electrons?
200
The exchange of this causes objects to become charged.
What is electrons?
200
The charge of an object with 8 positive charges and 6 negative charges.
What is positive 2?
200
This is the unit for charge.
What is a coulomb?
200
The direction field lines point in relation to a positive charge.
What is away?
200
This is created around a Van De Graaff Generator, causing lighter things to move towards it.
What is an electric field?
300
This occurs when a positive charge comes near another positive charge.
What is repel?
300
The charge of an object with 4 positive charges and 9 negative charges.
What is negative 5?
300
This happens to the electric force when a charge is quadrupled.
What is quadrupled?
300
The direction field lines point in relation to a negative charge.
What is towards?

What is the charge on the top of the dome of a Van de Graaff Generator?
What is positive?
400
Iron, Aluminum, and water are this.
What are conductors?
400
This is a method of charging that causes one side of the object to be positive and the other to be negative.
What is charging by polarization?
400
The answer to this question: What is the electric force between a (6.32x10^-6 ) c and (5.41x10^-7) c charge that are 7 meters apart? use (8.99x10^9) for K

This is why someone touching a Van de Graaf must be insulated from the ground to get their hair to stand.
What is they cannot be grounded?
500
Air, plastic, and rubber are this.
What are insulators?
500
The subatomic particle that does not have a charge.
What is a neutron?
500
This happens to the electric force when distance is tripled.
What is 1/9th the strength?
500
This does not create an electric field?
What is a neutral object?
500
This is created to allow charges to move from the Van De Graaf to someone else (even across air).
What is a voltage (or electric potential difference)?
