How Do You Calculate the Maxwell Stress Tensor Between Cylindrical Shells?

[tomfrank]

Homework Statement

x and y are nonconducting cylindrical shells. Both cylindrical shells are surrounding long wires that are carrying current. the x shell out of the page and the y shell into the page.
x radius has a charge per unit length = to +$$\lambda$$
y radius has a charge per unit length = to -$$\lambda$$
I need to calculate the maxwell stress tensor at a midway between x and y. (from the picture)

Homework Equations

T^ij =$$\epsilon$$_o(E_iE_j-$$\delta$$_ijE²)+(1/$$\mu$$)(B_iB_j-$$\delta$$_ijB²)

The Attempt at a Solution

How do I exactly found the i and j component of the magnetic and electric field?
