evenly distributed on its outer surface

An atom of oxygen has 8 protons and 10 electrons, this means the atom is ____________

negatively charged because it has excess electrons

positively charged because it has excess electrons

positively charged because it has a deficiency of electrons

negatively charged because it has a deficiency of electrons

What is the end result of charging by conduction?

Both object have the same charge, so they will repel one another

Both object have the same charge, so they will attract one another

Both object have the opposite charge, so they will attract one another

have a weaker affinity for electrons

During a physics lab, a plastic strip was rubbed with a sandwich bag and became positively charged. The correct explanation for why the plastic strip becomes positively charged is that ...

the plastic strip acquired extra protons from the sandwich bag.

the plastic strip acquired extra protons from the charging process

protons were created as the result of the charging process

Why does the child's hair stick up?

He gained a charge from the slide, and since he's not grounded, his hairs have the same charge so they repel one another

The boy is grounded since he's at the bottom of the slide

He gained a charge from the slide, and since he's not grounded, his hairs have opposite charges so they repel one another

When hair is neutral, some have a positive side and some have negative side, so they will attract to each other, making it stand up

What is the end result of charging by friction?

Both object have the opposite charge, so they will attract one another

Both object have the same charge, so they will attract one another

Both object have the same charge, so they will repel one another

Both object have the opposite charge, so they will repel one another

When a rubber rod is rubbed with rabbit fur, the rabbit fur acquires a positive charge because

electrons are transferred from the fur to the rod

protons are transferred from the fur to the rod

protons are transferred from the rod to the fur

electrons are transferred from the rod to the fur

Grounding happens when...

A charged object touches a much more massive object, usually linked to the Earth

A neutral object comes into contact with another neutral object

A charged object is rubbed against another charged object

A neutral object touches a much more massive object, usually linked to the Earth

When two objects are rubbed together, there is a transfer of electrons. What seems to be the important variable in determining which object acquires the transferred electrons?

The relative electron affinity that each object possesses.

The relative size of the two objects

The relative roughness of the two objects

The number of electrons initially possessed by each object.

Object A - the balloon - is made of vinyl. How does the electron affinity of vinyl compare to that of animal fur?

Vinyl has a greater affinity for electrons than animal fur

Animal fur has a greater affinity for electrons than vinyl.

Both vinyl and animal fur has the same affinity for electrons.

Nonsense! It is not possible to compare electron affinities with so little information.

In our electrostatics lab, a negative rubber rod is brought near but not touching the left-side aluminum can of two touching cans. Then the cans are separated from one another. What are the charges in the cans as a result of this induction?

left can is positive, right can is negative

left can is positive, right can is positive

left can is negative, right can is negative

Q A and Q B are two charges creating an electric field. Based on the electric field lines, we can conclude

Q A is positive and Q B is negative

Q A is negative and Q B is positive

Direction of electric field is shown (select two answers):

From positive charge to negative charge

From higher potential to lower potential

From charge negative to positive charge

From lower potential to higher potential

Which of the following statements is FALSE about electric field lines?

electric field lines are always straight lines

electric field lines cannot cross

electric field lines point away from positive charge

electric field lines show how a proton would move in an electric field

Which statement is incorrect ?

The closer the field lines are, the weaker the field.

The direction of electric field lines represents the direction that a positive charge would experience a force.

The distance between the lines represents the strength of the field.

An electric field is a region where a charged particle will experience a force
