Homework Statement 2. Equations v=q/4πrε 3. Attempt at solution Can I find the total charge by integrating the charge density equation from 0 to 2π and then plug that into the above equation?

Sorry, I meant epsilon naught.

Set the Qenc over E0 equal to E2πrL. When I did this, I got ρ0r/E0R. I know this is wrong because the homework is online and gives instant feedback. When I integrated, I got .5(2πρ0Lr)/R. I'm not sure where I went wrong.

Qenc?
