i don't get this question: rubber rods and fur define negative charges. explain this statement.

what is this question asking about???
can any plz tell me./?THX ALOT

The charge left on the rubber when rubbed with fur, was defined originally as "negative". It turns out, much later, these were found to be excess electrons, so electrons were called "negative". Such is the nature of origin of words. If you call a brown rock Xnepotia, and someone follows your lead, and it spreads, then some day someone will ask why brown rocks are called Xnepotia.

This question is asking about the relationship between rubber rods, fur, and negative charges. To explain this statement, let's break it down step by step:

1. Rubber rods and fur: When a rubber rod is rubbed against fur, electrons are transferred between the two materials. The rubber rod gains excess electrons from the fur during this process.

2. Define negative charges: Initially, the charge left on the rubber rod after rubbing it with fur was labeled as "negative." This designation was given before the discovery of atoms and subatomic particles.

3. The nature of origin of words: Over time, as the understanding of electricity and atomic structure developed, it was determined that the excess electrons gained by the rubber rod are responsible for the negative charge.

In summary, the statement is explaining that when a rubber rod is rubbed with fur, it acquires excess electrons, which are defined as negative charges. The designation of "negative" was given before the discovery of electrons and their role in electrical behavior.
