divide the stick in half, each half will have half the original
charge. If you split each of these halves, each piece will have
a quarter of the original charge. Ca

Answers should be given with an appropriate number of digits of accuracy.
If the problem gives two digits of accuracy for all of the given values then it
is incorrect to give many more digits in the answer. At most, one additiona

Our ancestors long ago recognized the motions of the planets through the sky, but it has
been only a few hundred years since we learned that Earth is also a planet that orbits the
Sun. Even then, we knew little about the o
