3 ways to charge objects: listening comprehension

par TM

When two neutral objects are rubbed together, what determines which object becomes negative?

Their relative electron affinities

The object with larger mass always becomes negative

The object that was moved faster becomes negative

It is determined by the ambient humidity level

In charging by contact, what sign does the contacted neutral object acquire compared to the charged object?

The same sign as the charged object

The opposite sign of the charged object

No net charge change

Alternating positive and negative areas only

After performing induction with a negative rod, grounding the sphere, removing the ground connection, and then removing the rod, what is the final net charge on the sphere?

Positive (opposite sign to the rod)

Neutral (no net charge)

Negative (same sign as the rod)

Alternating positive and negative stripes

Which of the following correctly lists the three methods of charging objects described in the video?

Friction (rubbing), contact (touching), induction

Conduction, polarization, electrolysis

Photoelectric effect, friction, grounding

Magnetization, friction, conduction

According to the triboelectric series explained in the video, which pairing is most likely to leave the fur positive after rubbing?

Plastic and fur

Glass and fur

Silk and fur

Rubber and fur
