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.
