## Homework Statement

A long straight metal rod has a radius of 5.00cm and a charge per unit length of 30.0nC/m. Find the electric field

a) 3.00cm

## The Attempt at a Solution

It says a) = 0

I did some math and I got

[tex]2k\frac{\lambda}{r}[/tex]

The rod is solid, so should a E-field be radially outward from its symmetrical axis?
