Coulomb's Law depends on __________ and __________
What is charge and distance
100

The law that states charge cannot be created or destroyed, it can only be transferred from one object to another, but the total charge must not change.

What is the law of conservation of charge?

200
The charge of an object with a deficiency of electrons
What is positive
200

Electric Field points in this direction around a negative charge.

What is towards?

All charge must be in integer multiples of this.

What is an elementary charge?

200
The electric force between two charges is strongest when the two charges are
What is closest
200

The type of force that exists between two electrons.

What is a repulsive electrostatic force?

300
The charge of an object with an excess of electrons

300

The force an electron will experience in an electric field whose strength is 4.0 x 105 N/C.

What is 6.4x10-14N?

300

Particle A and Particle B interact with each other. Particle A has twice the charge of particle B. Compared to the force on Particle A, the force on Particle B is

What is the same?

300
If the distance between the charge doubles the force will be
What is one fourth
300

An object has a charge of negative 1.92x10-18C. How many excess electrons does it have?

What is 12?

400
Every atom has a ________ charged nucleus surrounded by ________ charged electrons.
What is positively and negatively?
400

If a proton is placed in an electric field, will it move in the direction of the electric field, or in the opposite direction?

What is in the direction of the electric field?

400

The process of temporarily charging an insulator by bringing it near a charged object?

What is polarization?

400
This is the force of attraction if the distance between two charges is decreased to one third of the original distance and the charge of each is increased by three times.
What is 81 times greater?
400

The process of charging that involves bringing a charged object near a neutral object, and then touching the neutral object with a ground.

What is induction?

500
These are the three ways to transfer charge.
What is friction, induction, and conduction?
500

Two identical shaped conducting spheres A and B have the following charges: A: +8 B: -14A and B are touched together and separated. What is the final charge on each sphere?

What is -3C?

500

A positive charge and a negative charge held near each other are released. As they move, this happens to the force on each particle.

What is increase?

500

If the force between two charges is 10N, what would the force be if each charge was doubled and the distance was halved

What is 160N

500

A rod is brought near, but does not touch a neutral electroscope. The electroscope leaves separate. What charge, if any, does the rod have or can it not be determined?

It has a charge but the charge cannot be determined.
