Maxwell Stress Tensor

tomfrank

1. The problem statement, all variables and given/known data
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 lenght = to +[tex]\lambda[/tex]
y radius has a charge per unit lenght = to -[tex]\lambda[/tex]
I need to calculate the maxwell stress tensor at a midway between x and y. (from the picture)


2. Relevant equations

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

3. The attempt at a solution

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