Asked by Josh

If a segment of wire has a net charge (uniformly distributed), and then its length is increased by 50%,by what factor has its charge density changed?
If the original charge was 10.0 nC, how much charge must then be added to restore the wire’s original charge
density?
Answered by Damon
3/2 the length
same charge
so 2/3 the density

(3/2) * 10 = 30/2 = 15
so increase by 5 nC
Answered by Josh
How is it 3/2 the length?
