```				   Potential on the axis of a hollow cylinder
```

```										Dear student,
dV = K dQ / r, let dQ = sigma dA, use a geometric argument to get r.   Your dA here is going to have fixed radius (call it R ), so dA = R dz  dphi.  You have angular symmetry, so the integration of d phi is 2 pi.   This combines with K = 1 / (4 pi epsilon).   Your integration of dz will  run from -L/2 to L/2.  As a check, when z goes to infinity, you should get it to look like a point charge.  Probably by binomial expansion.

All the best.
