False

Front

T or F: When an object is charged by induction, electrons flow from the ground onto the object, or fro the object onto the ground

Back

Both directly on the magnitude of the charges and inversely on the square of the distance between the charges

Front

Coulomb's law says that the force between any two charges depends

Back

Electric Dipoles

Front

The charge distribution in some molecules is permanently separated in two regions, such molecules are called

Back

True

Front

T or F: Electric charge is neither created or destroyed but can be rearranged

Back

True

Front

T or F: The energy a charge possesses by virtue of its location is called electric potential energy

Back

False

Front

T or F: The direction of lines of force shows how large a force will be on a charge placed in an electric field

Back

Position

Front

Electric potential energy is the energy a charged object has because of its

Back

False

Front

T or F: Electrons and protons have the same charge and therefore attract each other

Back

More protons than electrons

Front

A positive ion has

Back

0.40N

An electric field has..

Back

The direction of the force on a test positive charge

Front

The direction of the force would act on a proton placed in both an electric field and gravitational field

Back

False

Front

T or F: A material is a good insulator if outer electrons of atoms in the material are free to roam around

Back

20N

Front

A 2-C charge and a 4-C charge attract each other with 10 N of force. How much will a 2-C charge and and 8-C charge attract each other when placed the same distance apart

Back

Two

Front

How many different kinds of force would act on a proton placed in both an electric field and a gravitational field.

Back

False

Front

T or F: an atom that is electrically polarized vibrates in only one direction

Back

Zero

Front

The net charge of an non ionized atom atom is

Back

Induced opposite charges in the wall are closer than other wall charges

Front

The reason a charged balloon will stick to a wall is that

Back

Distributed evenly over the sphere's surface

Front

Suppose you touch a negatively charged object to a metal sphere so that electrons move from the charged object onto the sphere. After far separation of the charged object, electrons on the sphere will be

Back

Protons and Neutrons

Front

Atomic nuclei of almost all atoms consist of

Back

False

Front

T or F: The unit of electric potential is the joule

Back

-1.6x10^-15

Front

10,000 electrons are removed from a neutral plastic ball. What is the charge of the ball?

Back

Accelerate away from each other

Front

If two negative charges are held close together and then released, the charges will

True

Front

T or F: When a change is placed in an electric field, the charge will experience a force.

Back

Tightly bound in place

Front

In a good insulator, electrons are usually
