## Homework Statement

Use Gauss’s law to determine a formula for the electric field outside (and far from the ends) of a long, uniformly charged cylinder of radius R and surface charge density σ C/m2.

## Homework Equations

I suppose

*net electric flux = ErA = Q/e0*

## The Attempt at a Solution

I solved for E, and then plugged in 4pi^2R^3h for A (surface area of cylinder). Just a blind stab in the dark.
