During a physics lab, a plastic strip was rubbed with cotton 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 cotton.

the plastic strip acquired extra protons from the charging process

protons were created as the result of the charging process

the plastic strip lost electrons to the cotton during the charging process

Consider the conduction charging shown.

Electrons move from the insulating stand into the sphere.

Protons move from the bar into the sphere.

Electrons move from the charged metal bar into the sphere.

Protons move from the sphere into the negatively charged bar.

A balloon is rubbed against a student's hair and then touched to a wall. The balloon sticks to the wall due to

magnetic forces between the particles of the balloon and the particles of the wall

electrostatic forces between the particles of the balloon and the particles of the wall

magnetic forces between the particles of the wall

electrostatic forces between the particles of the balloon

Two electrically charged identical-sized metal spheres, A (charge of -4) and B (charge of +8). If the spheres are brought into contact, which sphere will have a net gain of electrons?

both A and B

neither

only A

only B

A negatively charged rod touches the knob of a neutral electroscope. Which best represents the distribution of charge on the electroscope.

both the knob and leaves become positive

both the knob and leaves become negative

10.

assume a rubber rod is rubbed against a rabbit fur and gains 5 electrons. which of the following is true?

The fur lost 5 electrons

the fur gained 5 electrons

the fur gained 5 protons

The fur lost 2 electrons

11.

What method of static charging is shown in this picture

Contact

Friction

Grounding

Electron Shifting

12.

What is the end result of charging by friction?

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 attract one another

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

13.

After grounding, how will objects interact?

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

Both will be neutral, so they will attract one another

Botn will be neutral, so they will repel one another

Both will be neutral, so they will not attract nor repel

14.

Grounding happens when...

A neutral object comes into contact with another neutral object

A charged object is rubbed against another charged object

A neutral object touches a MASSIVE conductive object

A charged object touches a MASSIVE conductive object

15.
