The electric field 0.375 {\rm m} from a very long uniform line of charge is 830 {\rm N/C}.

How much charge is contained in a section of the line of length 1.70 {\rm cm}?

I started doing this problem, and though it was the right approach, but then i continually get the wrong answer, i have two more tries left. this is what i did:

I used the equation:

E = q/ 4*pi*E0*r[tex]^{}2[/tex]

and plugged in the electric field number given, with the known length of the line to get the charge of the particle... which came out to 1.30x10^-8 and from my own assumptions i thought regardless of what r is the charge should be the same, but it doesnt work. Can someone please help!!!
