# Potential of a conducting pipe#

The surface charge density on a long straight hollow metallic pipe is Ï. Assume the pipe has a diameter of $$2a$$.

## Part 1#

What is the electric potential inside the pipe? Choose the zero of electric potential to be a distance $$R_0>a$$ from the axis of the pipe.

You may copy the Greek symbols Ïµ0 and Ï into your symbolic expression.

What is the electric potential outside the pipe? Choose the zero of electric potential to be a distance $$R_0>a$$ from the axis of the pipe.
