Sandy rubs a rubber rod with a piece of animal fur. the total charge of the system before rubbing is zero. the system is made
up of the rubber rod and the fur. initially, the charge on the rod is zero and it is electrically neutral. the same is true for the fur.
when sandy rubs the rubber rod with the fur, the rubber rod acquires negative charges. how does the system change, overall,
based on the law of conservation of charge?
a)
the total charge of the system is now negative rather than neutral.
b)
although the rod becomes negatively charged, the piece of fur remains
neutral.
if the rod becomes negatively charged, then the fur becomes positively
charged.
d)
both the rod and the piece of fur have become negatively charged during
the rubbing
