## Homework Statement

## Homework Equations

E = 1/4([itex]\pi[/itex] [itex]\epsilon_{0}[/itex]) * [itex]\frac{p}{r^2}[/itex]

## The Attempt at a Solution

E = 2[itex]\pi[/itex][itex]r_{0}[/itex] [itex]\epsilon_{0}[/itex] = pl/[itex]\epsilon_{0}[/itex]

= [itex]\frac{pr}{2\pi r_{0} \epsilon_{0}}[/itex]

I am going by what I know about Gauss Law and using a similar format for the Electric field equation for a infinite charge line in a cylinder.

I fixed it little by little and I left off at:

E = [itex]\frac{r}{2 \epsilon_{0}}[/itex]

The hint it gives me is that i am missing p but putting p in the numerator or denominator will say it is not dependent on p.

I probably did something wrong in the process or used a wrong equation.
